So if I may put it out there I work for the shop so I haven't really had much time with this car to actually Rectify problems on it in very first time for giggles I Dynoed the car 3 days after buying it the engine has approximately 4000 miles on it. I know this for a fact I am the one who built it but I did not install it as a customer brought us the engine initially to rebuild. It has new housings all seals replaced stock port goopy Apex seals as he planned to turbo it originally. Apparently the car was experiencing a catalytic converter failure before I bought it and some of the cat substrate plugged the muffler. After he had tried to gut the cat , so the first run in the picture is 130 with pretty much a plugged up Muffler the second run was the after I removed the muffler. I plan to get coils plugs and a few other items did do a compression test at my shop compression is fine. I haven't had a chance to put it back on the rollers but I recently installed a mid pipe.

But looking at the graph it stays kind of low and once it gets to the top end where the auxiliary ports open it's very flat making 150 from 6300 ish until about 8,500
