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

 

those are impressive numbers, almost 340 Tq! put some LT headers on and pick up another 10-15

 

Those are some damn good numbers with BS mods, strong running LS1 ya got ther

Thanks for the comments guys I think for a 99 car with 110,000 miles she is running fine as wine I do have a set of mac mids i picked up for 100.00 bucks i need to clean and cut the ball flange off and they are ready to install with true duals. I am also in search of a used LS6 intake so if anyone knows of one let me know.

 

Very nice for such little work done to it.

 

Why does the dyno sheet say 11/23/2004???

 

Don't know why it does i guess they havent done the date on the computer.

 

lots of dyno sheets are dated like that.
the company dont care, they just collect data and print.

anyways, ****, i wanna get mine dyno'd now... id hope to be somewhere close to that.

 

Here is the video guys
