[QUOTE="CATDiezel, post: 1460407, member: 4387"] Anybody running these tunes? What's the skinny on GDP famous out of nowhere for the tuning world. I'm far removed and out of the loop. About given up on the former Spart-tan/patriot tuning.... I know there ridiculously busy but a half baked tune is just that.... everyone claims their exhaust brake works. Long story short, I'm happy with the former Warhammerx Raised shift point, the shifting was 99.9% flawless. Other than no pedal dampening and no exhaust brake (which I need)... and the famous p2074 code due to NL intake... which is odd, because I just proved yesterday it's not the NL 5" intake. They latest (yes it's beta) engine tune is more refined and smoother than ever but the trans tuning went the opposite direction from where they perfected it originally, unfortunately... So... Im considering changing tuners to either ppei or gdp. Would appreciate some feedback, thanks. [/QUOTE]
