I've been trying to find dyno graphs (pre and post tune) for the new DI 6.2L and can't find any.
Anybody with a BB tune on a dyno,
Care to post pre and post curves?

Most people with the 2015s won't have dyno sheets, as there are not many AWD dynos that can fit that vehicle.

My 15 XL Denali can choose 2WD. Isnt that the same on all????

That's right, forgot they are 4WD selectable rather than AWD now.

Also looking for AFR graphs... Seen a bunch of really lean "street" and "email" tunes that used just the narrow band O2 and seat of the pants tunes... Just one heat wave and or arco gas fill up away from a big knock event.

(Tunes on other non GM platforms)

I know this is an old(ish) thread but I've been pretty pleased with my KPE tune. Paid $450 for it and the tuner module to install it myself and it REALLY woke up my '15 Escalade.

It's another option for you guys to look into at least.

I've got their cat back exhaust coming soon too and will post up a video or 2 to show off the sound once I get it installed.

Did you get both the ECM and TCM tuned? KPE resells IPF tunes.
