It runs great so far my truck doesn't get that dead pedal at acceleration ex: merging on a freeway. Also the trans shift smoothly like stated before. I just finally uploaded mine today and tomorrow I will be doing some driving and see how it is.

Powerwise, the tunes feel real good and as strong/possibly stronger vs the custom and canned tunes I had beem previously running. I can only validate with the seat of my pants at this point. Tracks aren't open up here yet lol. Best way I can put it is the power delivery and shifting are awesome and compliment each other perfectly.

I figured out some tricks and have more fuel on tap while still holding max pressure compared to other stuff out there.

Can you write a tune for a larger vgt?

Yes but almost need the truck in my hands to get it right

It would be worth taking the truck to Matt for live tuning.

That won't be a problem

How do I acquire this tune for my '12?

WHY NOT · Mar 23, 2014

I have been running these for a little bit now and I am very happy with them. They defiantly make more power than the H&S tunes and shift every bit as smooth if not better. The shifts are quick and smooth not but not super harsh. I'll put it this way even my fiancé says they are smoother and more fun since they make more power.

I too have been running a couple different versions for a while and couldn't agree with you more.

Wish I would have checked this would have gotten it on a Dyno and hauled 2300 mile so ver the weekend. I'm interested I'll be giving you a call.

Ill be hooked to a trailer quite a bit the next two months as planting season nears, I have only had a small load on my GN with the tunes so far and the truck did well. I am hoping to get it to the track here soon too

Elliott6.7 · Mar 24, 2014

I pulled about 7,000#'s a couple of times and the tunes were good. No issues with egt's or boost. Trans shifted good under a bigger load.

I had no issues pulling 1,500 gallon water trailer this past weekend we were putting out pop up fertilizer I had my truck on tow tune. I had zero issues with egts I am running h&s blocker plates. Ran thru a tank of diesel I got about 15 mpg with it behind my truck.
