Plugged it in and selected stadge 2 ( 70hp ) went out to the hwy and noticed a strong difference, sets you back in your seat. Gonna try stage 3 when it warms up a bit...-28 CELCIUS this morning.... anyways i'm impressed and happy with the tuner. Its so simple to use and walks you through the program.

Go directly to stage 3, do not pass Go. Doesn't matter what the temperature is......

OK :D .....

gone to program 3 in bye ... ):h

Yeah, looking at the dyno chart you would not think it would be much difference in the power between level 2 and 3 but IMO there is a huge difference....I know my lly blows a LOT more smoke now...

There is another level besides 3?

3 is the highest.

I just ordered the Hypertech programmer and I am anxiously awaiting it. Is there much of a difference in power on take off or is it mostly at higher speeds, giving a "boost?"

I didnt think that there was anything other than setting 3?

Has anybody caused tranny problems (Limp or otherwise) with the HyperTech set at level 3? Are there any other drawbacks?

have 17k with mine, no problems at all, besides wanting more power now. I do run it hard on a regular basis. the 4-5 shift has a funky feel, so I usually back of on that shift.

I've had mine on level 3 from the first day I received it. I have never heard of anyone limping the Allison with the Hypertech. I think one of the reasons is that the torque is down compared to most others running the same horsepower gain. Just an example:
Hypertech power programmer LB7 level 3 = 96hp 163tq
Banks 6-gun with speedloader LB7 level 4 = 93hp (dyno uncorrected 240tq)

Tell me more about the power!! How is it off of the line? Will it light-em up?

RIGHT of the line from idle, there's a litte pause until the new found power hits you, as with most tuners. Of course, the turbo is to blame. This is with no power braking. Of course, it will spin the tires off the line if you do power brake. Once in a great while, I could get a small chirp from the tires when it shifted to 2nd, but most of the time not. My truck went from a 16.3 to a 15.4 1/4 time on stage 3. By comparison, which probably doesn't interest you, my 6-gun set on level 3 equals this time. I had no issues when I owned the Hypertech. I believe it's a well thought out programmer.

What scotty says kinda sums it up, just is so amazing to slowly drive down the street and get the revs up a bit, then hit the accelerator and feel it pull and pull hard, you know i can honestly say i don't really want anymore power out of it... my rear tires are taking a **** kicking as it is....and being able to plug it in and set back to stock in a minute if something ever comes up with no tracks left too . ;)

I agree pretty much with everyone here. I had an Edge system and just had too many problems and it started to make me mad. The hypertech on level 3 makes a touchy throttle, even touchier. Torque right off idle is noticable better than Edge juice on level 3. Power is strong through out the entire power band. Has great passing power and I never have tried to light'em up. I have absolutely no complaints about hypertech. I went right to level 3 and there is no wait till it warms up. I'am however very conscious about gettin into the throttle before it does warm up. It will embarass a GT mustang off the line up to about 75. I still have the EGT sensor plugged into the manifold that isnt hooked to anything. I'm still looking for a set of guages that look good with the tan interior with the bose sound system.

Had mine for over a year now....Level 3 of coarse. No problems or concerns. Runs great!


LATER!

Okay.....Just received the Hypertech 3 since my last post, suprisingly. It got here quicker than I thought. I have been playing with it since its arrival. I tried all three stages and DEFINATELY prefer stage 3. I was a little disapponted at first, only because I envisioned that I would take off like a rocket on stage 3, and "light'em up" with no problem. I had very high expectations, this being my first diesel and only putting about 1200 miles on so far. There is, however, a remarkable power difference at higher RPM's. The shifting is quite jerky on the 3rd level but I prefer the power and plan to keep her at this stage. I am very pleased with the results overall.

Questions, for anyone who knows....What are the actual dyno readings on stage 3 for the 2005 2500HD D/A 4x4? Does having a 4x4 make a difference? Hypertech's website has dyno readings for the 2004 1/2 - 2005 Duramax, BUT with a manual transmission (I think Allison numbers might be a little higher). I'll try emailing Hypertech and post their results if they are available. If anyone has already checked into it, though, it could save me a little trouble.

87 H.P. and 177 ft lbs TQ

I had problems with mine slipping the tran in the tow/haul mode when in level 3. Have you tried it that way yet (in tow/haul)?

I played with her very little in tow/haul at stage 3, but I did gun it several times without any issues. Maybe I'll have some issues later. As for now, I'm keeping it at stage 3. I'm not planning on towing anything heavy in the near future, though. Anyone else with a tow/hual mode issue?

the only time i take mine out of stage 3, is whene i am towing. had some jerky shifts at first and they smoothed out a bit after time. now after exhaust mods shifts very well. dont no why, dont cafe why, but i like it.

Hey guys, I have some questions. When driving normally, how is the throttle response? I can tell a difference in my stock truck when it gets to operating temp that the throttle gets more sensitve in town. I have a 31 tt that will weigh around 8000lbs when loaded and am thinking about this box for towing. I already have a set of guages from a friend of mine although several folks say you don't need them with this box. Does it make the engine sound any different? Idle or at highway speed?

Just curious as to what you guys think about using the HT III in stage 3 when only towing about 4K-6K lbs.?

I can't stand the Hypertech III in level 3 on my 2005. Step into it under load and it gets too aggressive in the timing. Quite raspy! Level 2 is pretty weak for my taste. That is carrying my Sportsman 700 in the bed and a 16' car trailer and a 4,000# compact utility trailer.

i take my h-tech down to stage 1 when towing. but my trailer weighs 15030lb. climbing mountain have to keep foot out of it and watch egts, can reach 1400 easy.

I've had my HTIII for 3 days now and here's what's what so far....stage 1 didn't do sh*&T for me, I couldn't notice any difference; stage 2 I could tell there was more power and the AT definitely shifted differently (from what I've read that's to be expected, especially with so little use so far); stage 3--all I can say is HOLY DOG BALLS, BATMAN! Now I see why you guys keep tinkering with this crap to get more power! The shifting was harder and quicker, but it set me back in my seat...and I liked it!

I also notice more of a diesel smell while it's just idleing in stage 3 in the driveway--but not much, and it's no big deal.

I'm headed to New Orleans in the morning and I'm pullin an empty 16' tandem that weighs around 1200-1400 (guess) lbs. I'm bringing back 3 aluminum duck boats that will probably weigh less than 5000 lbs all. I'm going to run it in stage 3 down and stage 2 back.

I run on level 3 for towing, about 7500-10000pds depending on which trailer. I have no issues with the trans to this point whether in th or od.

You will get higher egts in od so a pyro helps. Just throw it in th and the temps drop to around 1100 and your good to go.

I have only had to back off the power, that was up a grade in a 50 mph headwind at about 65 mphs.

I know some of the other programmers give more power, but for the $350 I paid you can't beat the deal.

I have my programmer on Stage 3 also. I'm running a 4" magnaflow exhaust, and the k & n cold air intake. I don't have any problems towing a 18' steel trailor with a 3000# car on it!!

I can't chech my egt's, but hopefully they aren't too bad!! No transmission slippage hauling the trailor either!!

I have a few questions about the hypertech. What are the differences in egts with and without exhaust/air intakes? and...What type of fuel mileage are you getting on each of the settings that you use?

Just got mine yesterday and the streets here were so slippery there was no point in getting crazy so I just stuck level 1 in to see if the programmer worked OK, and it did. Streets and highway dry today after work so took a spin on the highway, couldn't notice much differance although I thought the shifting was actually smoother. Slipping home to stick in level 3 changed that however as well as the power. While stepping on it going around the corner onto the highway access the back end broke loose! Let go a bit to regain traction and then tromped on it going up the on ramp and there is definately a differance. Getting back into town I noticed from a dead stop not a real improvement but punching the throttle in second gear causing it to downshift will break the tires loose and put you in the seat. Didn't notice excessive timing rattle in level 3. Anyway I didn't buy it to play around like I was so took it home and put level 1 back in for now, plan to use level 2 for towing - was just looking for that little bit extra and ability to change tire size and didn't want to pay the exhorbitant edge prices, although I really would have liked the juice/attitude combo. For the 227 US bucks I paid I think the Hypertech is pretty good value for the money!

I wish you could change your top speed limiter with the Programmer!!!!:( :(
Other than that, it's great!!
