No tune yet. Will be dyno & street tuned by John Vega of Phearable.net after the 1st ofthe year.

[Notes]
Full boost at 2200 rpm. Pulls real hard. Not much traction in 1st & 2nd at full throttle. Would expect whp to be in the 220-230hp range when tuned properly. Extremely fun to drive.

hey guys, im new to this sight, but ive been lookin everywhere for some answers and i just cant figure out wat is wrong with my car. i have a 91 prelude 2.0 si. i just got done putting a turbo on it. i got a garret t3 turbo, walbro 255 hpfp, obx 12-1 FMU, boost controller, FMIC. wen i was all done with the install, i took it for a test run... after i build up boost it just cuts off!! it feels like im stomping on the brakes. it gets up to full boost of 7psi, but it just cuts off. it does it in neutral too, if i rev it up high then let off then try to rev it up again, it wont. i was told i might need bigger injectors, so i put in some 450 cc injectors out of a dsm in and used a adjustable regulator to set the psi at idle. then took it for another drive and the same thing is happening. i cant figure out wat the problem is at all. if anyone has any ideas i would really appreciate the help!!!
thanx
