Hey buddy, good move on the Crane, I just drove my car today hard for the first time with the IC, overall the car is running really well, insane fast for the city streets I was on, but I think the Crane has really helped in overall response and power.

Hmm, very odd, have you tried that w/o the water injection, maybe you're injecting too much water?  Have you put 034efi in monitor mode, ensure that your temp sensors aren't cutting out in that range, that could cause a rich condition, just odd you're getting it in that narrow rpm range in only 2 gears.  Have you looked in the MAP matrix, I accidentally had miskeyed a value once in a cell and the car ran really crappy in a narrow range like that, check to make sure that's not the case?  Is your boost stable through that range?

Is your boost inconsistent, does it fluctuate, what do you think that would be a problem?

HTH,
