I get full spool about 9-10 psi at 5000rpm in 3rd and only about 5psi at 4000rpm. I know its not supposed to be this laggy. My set up is greddy downpipe, stock cat, 2.25 piping, dynomax muffler, tuned on crome 178whp on a mustang dyno (or about 200whp on a dynojet). I dont think I have any major boost leaks or pre turbo exhaust leaks, only a small leak on my downpipe. I have a brand new 1g dsm bov. The fact is I have no idea why my car is so laggy, has anyone else had similiar problems with the greddy kit.
