65972, Got kinda opposite problem of EclipseRST
Posted by 97TurboGS, Feb-25-04 01:22 PM
I am running 8 PSI of boost.

At WOT my car hits 8-9 PSI until you get to about 4500-5000 RPM then slowly drops down to about 5-6 PSI in every gear. I heard that running lean would cause this but when I get to 8 PSI, my fuel pressure is right at about 105-110 PSI. I would figure if I had a boost leak, My PSI would never get that high, so I kinda eliminated that. What do you guys think could cause boost drop-off at WOT?

if your boost is leaking down, you might have a hole in one of your couplers or something. i'd be willing to bet its your intercooler pipes leaking somewhere, possibly even the throttle body to intake mani gasket. definately a boost leak

Even if boost pressure holds at 8-9 PSI until you get to 5000 RPMs?

Could my wastegate be opening?

Can anyone help me? Or does everyone think it's a boost leak?

110psi of fuel pressure?! Holy shit...I'd recommend getting new injectors -- aside from your problem.
