Default New Bolt-on Numbers...

My mods are in the sig, I put down 340/357 STD today. This was in 100+ degree weather My AFR on the first run was 11.5:1, so we leaned it out to about 13:1 and picked up some more. Played with the timing some and picked up more hp but there was some detonation so we had to retard the timing a little and so we lost a little. Pretty happy with the results.

Also, I only lost 2 rwhp running a closed cutout, just a true testament to the flow capabilities of the hooker catback.

Not too bad for having cats and 100 degree weather I guess...

Great bolt-on numbers. Don't worry about the heat, that's what SAE correction factors are for.
