First of all my setup is a T2 2.2 in a daytona with an automatic. Mods are s60 turbo, taft s2 cam, front mount, 2.5 exhaust with a cat and no muffler. Heres the problem. I have been driving it around for a while now and sometimes it wont build boost from a stop even if I power brake for a while. Well tonight I decide to go to the track and the car just wouldnt build boost. It wouldnt even spin the tires in the bleach box. At the light it would sound like it was starting to spool but it never got there, it went to like 2psi and just stayed there. Once I left the lights it would start to build boost then it would all at once wake up and start hauling. I pulled into the pits to play around with the car and when I floored it while power braking it wouldnt spool but if I would let off the gas just a little it would spool right up. Have any ideas what it could be?
