There has been a few 11's and 12's with leaky rads, same issue as the 08 -10's. Leaking where the plastic end tanks attach to the aluminum rad. My 12 had to get a rad replaced as well as a frost plug that was weeping on the passenger side of the block. Sent from my SGH-I337M using Tapatalk

Trust me, not knocking SPE or their tuning... just thought I would share what I experienced when I switched directly from SPE Hot X tunes to Gearhead and how the truck reacted... it's obvious they are on the right track with their tuning, plenty of people are happily running them and their race...

Gearhead's trans tuning is spot-on! You won't be disappointed... Just an FYI, and I can't really figure out why, I was running the SPE Hot X files with no issues, then my Gearhead files showed up. When I loaded up the Gearhead files. Truck would almost pop into a "false neutral" on the 2-3...

I'm optimistic that this turbo will hang in there with the Gearhead and SPE files I use,tuning has come a long way, but when/if the turbo decides it's time to retire, one of the vendors will be getting a call. At this point, a single VGT looks like they work well. But.... after reading some...

I have seen up to 28-29 psi with Gearhead files. Heard somewhere the turbo is good for 30 and below. Getting in the neighborhood of 35 and you're asking for the turbo to scatter. I have put close to 15,000km on my Gearhead files with no ill effects. Sent from my SGH-I337M using Tapatalk

X 2 for Gearhead tunes. Have had mine for a while, does everything well. Great for dd'ing, towing, and everything in between. Sent from my SGH-I337M using Tapatalk

I'm thinking that code is telling you that your HPFP is hurt and on its way out. Sent from my SGH-I337M using Tapatalk

There is big difference in the custom tunes vs the canned H&S files. I have ran both Gearhead and SPE on my truck, I prefer the Gearhead files on my truck. But no matter who's files you go with, If you take the time to tell the tuner what you want changed or concerns you have with tuning, the...

Are you running the Hot X engine and trans files or the street files? Sent from my SGH-I337M using Tapatalk

I have read here on a few guys running down the track, not sure if anyone has run Matt's tunes over the rollers... Personally, I run the Gearhead tunes on my truck a majority of the time because the truck runs nice, and doesn't do anything strange on these files. The Gearhead tuning possesses...

X 2 for Gearhead. I have SPE files as well that I play with once in awhile, they're good but I always find myself going back to the Gearhead files. Great power and spot-on trans tuning. Sent from my SGH-I337M using Tapatalk

It probably didn't finish the re-gen the first go-around and commanded another re-gen when the conditions allowed. Sent from my SGH-I337M using Tapatalk

Aren't the 6R's a little different in shift patterns as well as in the pan vs the 5r's? I would agree 1st could be eliminated, more so on the 6r.... Sent from my SGH-I337M using Tapatalk

That's kinda disappointing to hear for the folks not intending to modify their 15's. But, sounds like it will be a better platform to start with for mods. I'm wondering if the lag (DPF present) can be taken out or, at the very least, lessened with some different tuning? Sorry for the de-rail...

On post #6 it was stated that they were still experimenting with trans files as well as engine files and figured it will get quicker with more testing and passes down the track... Sent from my SGH-I337M using Tapatalk
