I have posted a couple times before, my setup is 91 lx 5.0 150000 miles, aod. Motor is stock lower w/trick flow track heat heads, 1.7 rr, stage 1 cam, bbk ssi manifold, 70 mm throttle, stock 19lb injectors, stock mass air, cold air, shorties, offroad h, flows.

The problem is the car doesn't idle great, i've chased vacuum leaks, changed fuel pressure and timing, and i've never gotten it to make the power it should. Its got new o2 sensors, good gaskets everywhere, i believe no vacuum leaks, what's going on here? If i had to guess, it's probably making around 275 crank hp, cause it barely out runs mach 1's w/5 speeds. ( my car is lightened, no ac smog power steering 3.73 gear)

This leads me to think i need a professional tuner. I am located in reno, nv, but will be moving to knoxville, tn within a month. Where can i take it for some dyno time? Who's had good experiences? What kind of a tuning chip, etc, can you use on my computer?

try performance resource, I had a chip made for my old camaro, and was happy with 'em. www.performanceresource.com

you siad it right there... you think your making 275 hp, if you take it to a dyno tune shop , and most big towns have one. they can tell you your HP and if your running rich or lean and what RPM your makeing power, etc
and alot of them can even tune your PCM there to max out power.
theres a catch. there not cheap. big bucks most of the time

You have nothing bolted on there to require a tune. I made 500whp with out a tune. Find your idle problem and save the cash for mods.

check iac and maf, or if you think its a vacum leak, start your car when its cold take a can of brake clean and spray were you think a leak can be comming from. spray around your in take to make sure its not leaking
