Hello!

i've got a 2011 GMC Sierra 1500 with LT headers, 3" exhaust, and a k&n intake. I'm soon installing a cam, valve springs, trunion kit for rockers, and pushrods. I've also got the diablosport inTuner.

I've used the inTuner to firm up each shift. I know that fast shifts will prevent a build up of heat and be better for the transmission. My question is at what point do I need to worry about strengthening this stock transmission? My next upgrade wil be an edelbrock TVS2200 supercharger getting me to the 600hp mark.

Am I good to go now with firm shift pionts? Will I be good after a supercharger?

Basically I don't want to kill my transmission. How do I get the most life out of it?

Thank youu!
