Payback hits the chassis dyno

[Vegas69]

Had a great day. AJ rode over to the dyno shop with me and Curtis met us over there. Got her up on the dyno and made my first run. I had the jetting perfect. He was very experienced in drag racing and tuning and said don't touch the jets. I then added timing a few times, bumped the rev chip, and removed the air cleaner. It really liked the timing. I ended up with 41 total and just couldn't go any farther on pump gas. It wasn't detonating but it's loud! I wanted to He said the air here sucks and I'd see 20 hp and ftlbs in Cali. My favorite part is 497 ftlbs at 3800 rpm!!!! 491 horse doesn't suck either. Very happy with the performance. I'm sure it will be asked.
