So here's my situation. I have a 2013 escalade esv with full bolt ons. Headers Vararam ls3 throttle body custom dual x pipe exhaust. Badass 93 and e85 tune. I just ran a 13.9 at 100 at the strip Friday on a set of 17s. No joke. I have the opportunity to trade up to a 2015 Yukon Denali xl with the new L86 6.2. I would do the same mods to this one for sure. I'm thinking it would be faster than the escalade is but I'm not sure. OR I could keep the escalade and cam/stall it? What would you guys do? I'm torn. I love the escalade. But if the Denali would be faster I'm all for it. I'm nervous to tear into the escalade. My tuning guy tuned a stock crew cab 2015 Silverado and it ran a 13.6. Stock with a tune only....

 

If your tuning guy did that to a bone stock 15 CC, then it's a no brainier! Seems like you could be running a better time with the 15 Denali with just a tune, then your 13 escalade! From what your telling us, With full bolt owns and a tune from your guy, you should see very low 13's with the 15 Denali! Go for it

 

I would think trading back such a new Escalade would be kind of an expensive endeavor! But I also think the new 6.2/8 speed has more potential than your Escalade does. The problem with the current 8 speed cars is they come with 3.23 gears which negates the benefit you would think the 8 speed gives you off the line.
