where's that info at? Did they write or publish a paper? I haven't been able to find anything on this. Any info would be great.

Well what I was considering was having the car on 2 different settings. DD it on like 12 PSI and only turn it up when I go to the track. That way I don't leave 200ft of rubber when I try to pull on to a road quickly.

Is their another ECU brand you would recommend over the Microtech because of this flaw? Any idea when their going to release a new version to fix this?

As stated in the reply to the first thing you said, I was thinking about it and I agree with you on this one. I'm only going to have it set to 12 PSI for DD and it's looking like around 16-18 PSI at the track for what I want for my power goals. Also, won't running AI at the track yield me even higher hp when in full boost because of the lower temperatures?

Ah, I didn't realize it was a drag car that would only see full power for a few seconds at a time. When you said track I was thinking of circuits where you'd be wailing on it for 20 minutes at a time.

You tryin to be J-Rat jr haha....get a descent size turbo like a .84 like stated before, tune it to 15psi and have fun!!! Basically what people are telling you is that you gotta choose one or the other DD or track??? My choice would be mid size turbo on a half bridge with a tune on a Haltech....beat all the muscle cars in town and call it a day on not an insane amount of DD boost like 20

BTW you might wanna go with a proven engine builder like BDC Motorsports...Brain does some of the most beautiful port work around hands down and his prices are very reasonable
