so i tuned my stepmoms 08 LMM. ive tuned alot of LS cars but first diesel. ive read instructions and followed carefully now just asking for second opinion. it has 35" tires and a 7" lift. its a dog. stock 0-60 was 11 flat and i cut it down to 9-9.30 seconds. very little tiny poof if you hammer down from dead stop other than that no smoke. i was wodering if they where any tricks to a litle more safe power? she was wondering if there was any way to get a little more smoke of the line before the turbo spools. thank you for looking.Kims Duramax.hpt
