2015 lag vs 2014

[Mr.BigOil]

in the short time I've had my '15, I think the 'turbo lag' may be more in the function of the transmission shift strategy.

It definitely runs up through the gears quick...simply tuning a different trans shift strategy would almost certainly add 'boost' without touching the fueling tables.

Not reading past this post, you are 100% correct.
Back in November, I tested a shift strategy tune(trans only, no fuel added).It was more impressive then the SCT performance tune. No lag.

I know in my stock 15, if I'm dead stopped and turning left across traffic I've had a few white knuckle moments because of the lag.

This definitely is one of those times when I feel someone should yell..

Swap a 4r100 in it!

Trans tune 2-4-6. No need for the odd numbered gears.

That's not turbo lag. That's has to do with traction control or what not. I just make sure to turn it off every time I get in the truck.
