I'm asking as your dyno numbers are exactly like a 90 that I inquired about. He had a P&P to the plenum and I/H's and a chip and headers w/o cats. The P&P and chip was mail order from Mr. Haibeck's shop and the owner did his own assembly work. His heads & cams were not touched, and his dyno sheets which he posted in his add were right at a 365 hp avg for three runs. I don't remember the brand of headers and the exhaust....  ...it was a long time ago.

365 at the wheels???
Somethin' ain't right!! Mine dyno'ed last fall at 339 stock (except for a Borla cat-back). I don't know what it is at now - soon to find out - but w/ top end porting and Marc H's chip, and not changing the stock exhaust, turned my 90 into a whole new animal! I would think it should be between 390 and 400...NOT 365, if the dyno graphs posted on Marc's wall are any indication.
