Well, first tuning run completed. Happy with the results, I guess. I hit 20 PSI for the first time ever. Couldn't enjoy it though, for some reason right around 18 PSI (rough guess, because it built WAY fast, even in 4th!), it started hesitating and would then backfire and nearly shut down completely. I think it maye be my settings fucked up on the EBC, or possibly not a BCC installed...which would be stupid, but considering everything else this car had done to it wrong, not unbelievable.
PS- My settings were as follows:
LO
SET = 50%
GAIN = 10%
START BOOST = 150 (15psi)
WARN = 180 (18psi)
LOWER = 50%

For those who can decipher this and see something blatantly wrong, let me know!
