boost leak or wanked afm etc?

[s15_spec_r]

story story
boost gauge reads .6bar but the car doesnt pull at all, only reachs full boost at around 4800rpm and then hits the rev limiter at 5000rpm, idles fine and doesnt missfire, turbo is spooling just no power at alll

any ideas?

If it was boost leak it would never reach fool boost and if you open your window should hear it, i'd be looking elsewhere, it is possible for the afm to be the trouble, hope this helps

true enuf, the more i think of the symtoms in my head the more i think its an afm, hopefully
