The other day i fired up my 88 and it has been sitting for awhile, as i haven't gotten around to putting the new exhaust on. i cut the whole exhaust system off except for the stock down pipe. i was revving it up and noticed the boost gauge was jumping to over 15psi. i didn't really think an engine would boost much in neutral.

I am surprised that it is boosting that much with no load on the engine. What turbo? Stock IHI? Are you sure ignition timing and cam timing are correct? SPOUT plug in? Is the timing advancing to 25 to 30 degrees BTDC when you rev it in neutral?
