UPDATE: I am seeing full boost at 5,300RPM which really sucks. Does anyone know how I can fix this? Is it the FMIC? I see someone else with the same turbo making full boost at 3,400rpm. http://legacygt.com/forums/showthrea...ek-171262.html

Yeah I know you said that already but why? Wouldn't there be detonation or some kind of better indication?

Ever since I started tuning it almost a year ago there was only slight knock once in while and it was tuned out. The lag has always been the same. Do you live in Houston?

How quickly does the vacuum guage jump to 0 when you hit the throttle from an idle? It should be almost instant no matter if you're coasting or idling...good luck man, also keep an eye on oil pressure

Yes I have been sealing leaks all day and the vacuum is now at 18 with the AC on and 22 with it off at idle.

if there is raw exhaust coming outta the oil filler tube with the engine running at operating temp, there are 1 or more pistons with bad ringlands and you would have to have a pretty bad leak to get that slow a spool...either a boost leak---it would run real rich on boost....or an exhaust leak pre turbo...and that would be LOUD and leave carbon/scorch marks where it is leaking

and/or the tune is so far off that it isnt ever gonna spool without a real tune

with a vacuum leak its going to run horrible more than likely. what kind of manifold and turbo are you running? also what about exhaust. obviously and i may be stating the obvious your exhaust is what powers the turbo if your engine isnt exhaling properly your not going to spin that turbo adequatly. my expertise is mainly from nissans primarly the rb25 but a turbo setup is a turbo setup. if the turbo is too big or the exhaust is impedded its going to slow the spool. also is the turbo a journal or ball bearing? journals will also spool slower. but tend to be cheaper. your graph looks to be pretty linear though. at least to me.
