: some H&S questions

Im on the fence about doing a DPF delete and the h&s or just doing the H&S for now and then eventually going to the DPF delete. Main things that im wondering:

If dpf is present, do you still get better fuel econ? or does the truck regen more and it actually gets worse? Can you feel the performance increase in driveability?

If you get the non dpf delete, do you just get an unlock code from H&S to make your tuner upgraded to emisions delete?

I read that if the speed limiter is removed that you loose cruise control function. Do you have to remove the speed limiter, or do you have the option to keep that to keep your cruise?

Thanks for any help!

Possible to get better mileage with a tuner with the DPF but all depends on the tuning. The cleaner it can be and the easier you drive it that may do the trick. But if you get on it hard a lot then plan on more DPF regen time. HP increase you will most likely feel it. No idea on the rest of the questions.

You can choose to leave the limiter in place to retain cruise control. I haven't gained any mileage with the DPF on. You can feel an increase in power.

Email h&s. I did and they said.
Thank you for your interest in our products. What products you will need depends on what you are looking to do. If you are just looking to increase the power of your truck you would only need one of our tuners. Our DPF present tuning gives you a 40HP or 80HP increase in power along with improved throttle response. If you are looking for increased power as well as disabling the EGR and Urea systems and removing the DPF you would need one of our tuners, a DPF delete exhaust kit and a software unlock code. Our tuners range in price from $699.00-$1299.00, exhaust kits from $369.00-$635.00 and the software unlock code costs $100.00. The tuning is identical on all 3 of our tuners so it comes down to the features of the tuner itself. A few important things to remember with the LML tuning are 1) If you select to remove the speed limiter it will also disable your cruise control, exhaust brake and cause erratic fuel level readings. 2) There is no tire size adjustability and 3) The power levels are not shift on-the-fly even with the Mini Maxx and Black Maxx. We are working frivolously to overcome these obstacles but are not able to say if or when that will happen.

I am not in the market - but i do like to read the threads on the performance..... here and at H&S

I have noticed the Black Maxx has been out of stock for several weeks .......... figured i would ask around about it as it seems a bit odd.......

I wonder which one they meant. :D

I think a better adverb to use in that case would have been "diligently". :D

Hoping all is well and simply a supply chain issue :)

Stupid question here. What is this speed limiter and why does it need to be disabled? Cant go fast enough I am assuming?

Dm23

It's like a governor pre set at 98 mph. From the factory. But idk why it needs to be disabled.

We give the choice to remove it for guys that need to run down the track or on a dyno at speeds greater than 98mph. We do dyno testing in 5th gear, which will need the speed limit removed to get full RPM range.

Most customers leave the speed limit function in place, so as not to lose cruise or turbo brake. It is an option that is entirely up to the end user. No one else on the market offers a speed limit removal option for the LML/LGH platform. Just one more way that H&S is trying to provide the end user with as many options as possible to cater to their needs.

Mini Maxx went on friday. So far i am pretty impressed. I put it on the mild tune. fuel econ didnt go up much, but i can say i notice a difference in turbo sound and performance. I am running it w/ dpf present.

One question for the H&S...did you guys notice more regen time w/ the tune in place? Also is there an option to return the truck to stock when it is serviced? Can they tell if a tuner was present?

Thanks for all the help.

I'm not H&S but I can answer some of ur questions. Yes u can return to stock and YES the dealer can tell if a tuner was used. If anything were to happen.

DM23 is correct. Almost since the dawn of ECUs, the manufacturer can tell if it has been tampered with, IF they want to dig deep enough. It is all a matter of how picky your particular dealer is, and what you are trying to get warrantied. If you go in for a malfunctioning blower motor in for your climate control, I would hope the dealer would look past the fact that the truck is tuned and fix the problem anyways. Powertrain issues will be another story though.

Your best bet is to call your local dealer and ask them what their view is on aftermarket exhaust and tuning on a new LML. Sometimes they will be straight up with you and let you leave all the aftermarket parts on the truck when it comes in for service.

What is H&S doing with my VIN code? Why is this required to order the LML download?

Dm23
02-29-2012, 07:39 PM
Its if ur doing the dpf delete It requires you to give the vin. So they can specially program the dpf delete to YOUR truck. If ur not doing the delete then u don't need it

adam52904

I too am interested to know why they need it. If I had to guess it's an acknowledgment that you are using it "off road". Why the extra 100 bucks on a $1000 tuner....that I'm not sure.

When I ordered mine there was no Customized tuning to my truck. I ordered thr dpf present tuner then ordered the unlock code.

Dm23
02-29-2012, 07:44 PM
Just to program ur vin for the dpF delete to work

02-29-2012, 07:45 PM
What did u order anyway ?

adam52904
02-29-2012, 07:48 PM
I at first purchased the h&s mini maxx and tuned it w dpf present. I just ordered a Mbrp turbo back delete so to get ready for that I got the unlock code.

An problems with the mini maxx. And hows ur truck running with the dpf still there. Any complaints ??? Bc I plan on getting it to.

adam52904
02-29-2012, 08:13 PM
No complaints I've had no problems. And the performance has been great. I'll have more info in a week when the delete pipe is in

Ok cool man. Keep me posted or PM me when u have wary thing installed Bc were probably going to have the same set up lol. But Did u have the pyro installed yet ?

adam52904
02-29-2012, 08:23 PM
I just use the factory ones that the h@s pick up for now but will install then once I have the Mbrp in

Ok. What level are you running ?

adam52904
02-29-2012, 08:30 PM
Just mild. Plan on running stock (I heard in the tunes there is a lot or turbo noise at idle) or maybe a 50hp depending on the idle sound.

Dm23
02-29-2012, 08:34 PM
I've never heard any body say that. But. Ya I plan on running stock level after the dpf is gone. All I'm lookin for is the good turbo sound

02-29-2012, 09:25 PM
It will sound the same at idle no matter what. The turbo vane position is not changed.

H&S - is the Black Maxx screen going away? Is Mini Maxx staying? are you switching to a new case and screen? i am not implying you are shutting down or anything like that - i dont want to start comments to that line or anything......... i simply know I have been asking about it as i have seen it on back order for 6 weeks or so........

Curious about how things will be handled after warranty with it -will it be able to be repaired - will parts be available, or will it be a dinosaur and those who have it would have to switch to mini or what ever would be available at that time? and or would there be any incentive/compensation on switch? just curious because i believe my frined may be with in 30 day policy or just out of it.......

Thanks for the great work you guys are doing on keeping options open for owners.....

ive read 40-80- hp , are you able to run 80hp without changing anything on the motor? whats the torque #,s at 80 hp? new to diesels. may want some more go soon. how far can you push the stock fuel system and turbo with the LML,s? thx dan

@ clarkely. This is for you

The reason alot of our tuners are on back order is simply because we are experiencing an incredible growth spurt and are unable to keep up with production. We also have a new tuner in R&D to replace the Black Maxx which will be available hopefully by August. Not only are we not going to stop selling the tuners but quite the opposite!
