I have a 2003 Silverado 2500HD with the 6.0 and NV4500. I got my HP tuner today and copied my 2004 GMC Savannah 2500HD rev limiter onto my truck so it’ll bounce and not just cut the fuel. I’m just wondering what do I need to do to squeeze out the max power I can before I do a cam and heads because it’ll probably be a while before I do that. It does have aftermarket wiseco pistons that did raise the compression a little bit
Edit: forgot to mention I want to eliminate the throttle lag as it is a drive by wire
