Long story short. After getting his azz handed to him for the last few years my dummy buddy bought a TM8 (Maybe an 09 or 10) with a BD turbo setup. Typical BS of "its the best ever, fastest around, blah blah.. Its been out 4 times now, and more or less ruined 4 ride as we cater to this idiot as he blindly tunes it. Can someone give me some starting points on the RPM/Fuel numbers? We ride at 6k (ish) feet, its at what I can tell 8 PSI on straight 100LL fuel. It ran reasonable one ride, and now once you blurble its way through the bottom will light up and pull, then magically just sign off as if its on one cyld. AFRs spike as if its not getting fuel (this condition was new last ride) Im sure there are a million and seven things possible and Im somewhat savy with some of this crap so Im going to go over the mess this week, but looking for some obvious signs suggestions. Any thoughts are welcome. (Ive already suggested to burn it to the ground. Hes not sure thats a great plan yet)
