Sup? I got an 89 IROC with TPI 350. The previous owner did a few upgrades including, intake runners (no name on them?), pulled the screens from the MAF sensor (or whatever sensor is after the air filters), air foil thing, adjustable fuel pressure regulator... I currently got some extra cash and I have been tuning up the car, can anyone recommend a suitable fuel pressure? I played around with it a bit and used the chart in the tech sections but it didn't seem to run too much different. I also checked my timing and it reads 25 degrees at normal temp with the A+B jumped inside the car. My manual says six? Do my mods make any difference?

Also, sometimes my car revs high until I quickly tap the gas and it drops? Is something sticking or is this normal?
Thanx a lot.

Owner of a 1989 IROC-Z Camaro, a.k.a. "The Babe Magnet". Painted a cheap metallic blue that chips off all too easily and covers over the IROC-Z decals on the doors, also has non-leaking T-tops, ps, pw, power rear hatch, working A/C. Mods: SLP intake runners, gutted MAF sensor, adjustable fuel pressure regulator, modified air spoil, 3.27 posi rear end.
Broken stuff: rear spoiler brake light, driver side lock, power antenna, tilt steering, rear end bushings, cracked passanger side ground effect, washer fluid tab, leaking exhaust and a rotted through muffler that sparks when the car bottoms out while driving like any 17 year old does.

 

AS far as the car revving High, THats called Fast idle, perfectly Normal.

I hear ppl like about 46 psi, But I don't really know.
