Hi Guys.
Thanks for your help. I have towed with our 2006 LBZ Dually our 10K 5th wheel with Hypertec on level 2 up steep grades and never had a problem. Egts were below 1200. Has any one had a problem towing with Hypertec on level 3 with egts, or limping trannie with LBZ? Planning on taking a trip with some steep long grades and was wondering if I should try towing on level 3.
Thanks Ron

I pulled about 9000 lbs with my 04.5 LLY on level 3 and never saw temps above 1250 while climbing grades at highway speeds.

Hypertech is made for towing!!

I have towed up to 14k of salt on a flatbed trailer at speeds up to 70 mph and no issues. Hypertech has been stuck on level three for over 4 months now and no issues other than lack of rubber on tires. It is a great tune for the money. And it puts out more power than what they say, atleast on my truck.

What actually happens when the tranny goes into limp mode? is the rpm limited, gear choice reduced, top speed governd????

I had the HT on my 04 LB7 and did not see much in the way of improved MPG. It did tow on level 3 without exessive EGT. On my 06 LBZ I am running DS Predator on 85HP setting but I run water injection to keep EGT safe. I get about 3MPG better with that setting. What MPG improvement do you get with the HT on your LBZ? I get 20MPG HWY and 12 to 13 towing with the DS. This is about what I got with the 04 GMC reg. cab 2500 4x4 and the HT on level 3 which was about 1 MPG improve over stock. (DS on 120 I get EGR codes some times and always high EGT's even w/ water inj.)

So far the best MPG i have seen since hypertech was 19.2 and that was about 70/30 hwy/city. I have made three trips down to FL and was around 14.5 the first with about 8k on a trailer, right around 16 the second time with only 5k on the trailer and got 17ish with a bed completely full and a make shift box that was 10" taller than my cab, little bit of drag. all those trips were made with cruise set at 75. Around the city i generally get about 15 but since its been cold and I let the truck get warm before leaving and usually sleep in my truck during the week on my lunch break it has alot of idle time and low MPG. I was at 12.2 last fill up with very cold temps and long idle time.

No problems, so far.

bronson: My expereience with limp mode was there was a noticible reduction in engine power follwed by the tranny not letting me out of 3rd gear.

been on level 3 for around 7k with no problems. I too was wondering if anyone has damaged a truck with the hypertec. Replies look good so far so I guess i am clear for take off!!

I have limped my tranny three times with the hypertech on lvl. 3. Mostly just driving around. First time I was running a powerstroke down the highway and it limped coming out of 5th. Everytime since it has happened at little easier, but always on the 5-4 shift. So i would be careful with WOT 4-5 or 5-4 it definately can cause damage.

Limped Trans With Hypertec On Level 3

I Wonder if their is a difference between Lbz 6 speed and 05 & 04 5 speeds? Has anyone limped trans with Hypertec with a six speed lbz? Just wondering.
Thanks Ron

off topic, but programming the hypertech for the smallest tires and lowest gears would give 10% more warranty! That would go along way on the '07's.
