My 6.0 is way to high compression for a turbo. I'm contempt with my NA setup. Us there's not a single good tuner in Canada, Justin and I do our best but I wouldn't want a 650rwhp email . Ive never been big on having massive power cars, my biz partner ha a 760rwhp gt500 and it doesn't do much for me
Let us not forget I have had turbo cars that moved pretty good, my legacy made 320awhp with the AVO 380. ITs fun yes, but in a truck Id rather have my aggresive NA motor. Theres always someone out there thats faster then you.
I hope you follow through and build a rcsb duramax
