What is the Difference Between a Corvette 6.2 and a Denali 6.2?

[jimstem]

So given all that, is there a way to take that 6.2 in the Denali (or starting in 2018 with the Tahoe RST package) up to the same output as the Corvette, without adding a supercharger? I'm surprised there isn't a kit or something that basically transforms the SUV 6.2 into the Corvette 6.2 output.... or maybe I'm missing something....

ECM tune & TCM tune would be the biggest bang for the buck in terms of getting a GMTK2xx 6.2L closer to 'vette 6.2L output parity.
If you specify that you'll never use 87 octane , or 87 & 89 octanes, the engine tune can be considerably improved.
As for the TCM, GM programs it to maximize MpGs, meaning less fun.
A TCM tune may lower the peak possible mileage by 2 or even 3MpG, but the transmission will become more responsive, improving Smiles per Gallon.

I'm still confused as to why more of y'all ain't gotten your vehicles tuned yet ...
