All you can do is ask. I can't say he's always gotten everything right the 1st time...but has been willing to work with me on everything thats come up and has sent half a dozen files or more to get mine fairly dialed in. W/O putting it on the rack (dyno) its hard to say its "peak" tuned. Just ask for Allen.

Thanks, I'll give them a call. Ok I fired it up and feathered the throttle for 3 or 4 minutes and then it would idle on its on. I let it idle for about 5 mins while I checked the fluids and adjusted the fuel pressure. After that was done, I shut it off and then tried to restart it. It wouldn't start unless I feathered the gas pedal and then I had to keep messing with the pedal to keep it idling. When I shut it off, I checked the codes and I had two P0300s and P0174.....
