so i just bought this 07 cummins starts and runs great i just instaled a edge juice w attitude and its acting like a stock truck until i get to 2200 rpm then it takes off like a rocket until it hits the rev limiter. barely blows any smoke even on stage 5 until it gets around 2200 rpm then a little poof and thats it. no codes other than a low boost sensor pops up every once in a while
