My car is not getting much boost until 3500rpm. I have the GT525 from Z1(I'm disappointed to find out they sold me turbos with carbon seals but I guess thats my fault for not asking) and have less than 1K miles on them. I'm not building boost until 3500rpm. After that its like someone flipped a switch and the car is a beast. I have not tuned the car yet on the dyno but my wideband looks good around 12 to 1. Is this something I'm going to be able to fix with timing? My buddies car kills mine with sport 5's even if we swap ecu's(he has a JWT and I have the ZEM). I've also had a ton of problems with the ZEM but the guys at [ http://xtronics.com/ ] took care of it since ASH would not return my emails.
