Ok, I got mad and set my timing on my 89 IROC back to twenty eight degrees advanced timing as that was what it was at before i went to fix it and set it back to stock... after setting it to 6 degrees i had an over all loss of performance... what gives?

------------------
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.

 

Are you disconnecting the tan wire before setting the timing?

 

And I'd verify TDC vs. the timing mark and tab...balancer may have slipped.
