99 Z28 Dyno results

Well finally got the Z dynoed today I am happy with the results real happy since i only have free mods, lid, off road y and dumped bullet muffler. 329.6hp/339.6tq the guys at RPM said that it was damn good for a 99 LS1 they were really impressed with the A/F ratio

they think it has been tuned sometime. I don't think it was cause i bought it from my buddy and when he got it from car max it was bone stock down to the paper filter. I post the video as soon as i get it. here is the graph

That's great numbers. I only got 305rwhp and I have a catback, lid, and RP fluids everywhere.

Thanks for the comments guys, yea i was impressed with the numbers and how perfect my A/F ratio was. I do have a set mac mids i picked up for $100.00 I need to clean and cut the ball flange off then they are ready to be installed with true duals, also in the hunt for a LS6 intake. But for a car with 110,000 miles and pretty close to stock she is still running fine as wine
