Hey guys I got a 99 z28 m6 with a lid, QTP LTs, QTP Catted YP, and GMMG... The car has about 93,000 miles on it... I was just wondering what kind of dyno numbers I should expect with this set up. I've yet to have it dynoed so I can't tell you what it gave me stock. Any help is better than no help.

My numbers are in my sig. I had 117k when I had it dynoed. Only difference is I didn't have cats.

I have the mods in my sig and ran this:

It seems low to me, but maybe not...

Anywhere from 310-340 I would say. All depends on the car, obviously
