402 ls2 Firehawk dyno results
Last week i had the Firehawk tuned at APS Racing in Oklahoma City on their Mustang dyno. I let them know that i wanted it to be as drivable on the street as possible as it would be my DD for now. They did great, and it really doesn't buck unless your under 1,500 rpm and it still makes great power.

This most recent session it was at about 12.5k, so yes. However, the previous owner had it tuned when it was built and had a much larger cam. I'm assuming it didn't have many miles on it at that point.
I haven't, as i've only had it a week and a half. Previous owner had best time of 11.3 on the strip.
There are some details i'm not sure of, like the intake. I believe it is an ls6, but am not sure. It had a custom grind cam in it when i bought it (256/264 .609/.601 113) but it was WAY to big. I drive this thing daily and wanted something that makes good power but is actually streetable. As for the exhaust, the dual/dual does have a cutout just before the muffler. I've opened it a couple times, but there is no way i'm leaving that off for any period of time...it's insanely loud. I plan to get a different catback asap, most likely a magnaflow.

yea vindicator is a good cam for this setup. I would like to know what intake you have on the car as well. And also ihave been on md dynos and dyno jets. the mddyno seems to load the car more there for dropping the rpm peak. so mine on a dyno jet was 7200 then it would fall off. mustang dyno 6900 then fall off. so if you up grade the intake to a 102 i am sure you can gain a nice 8 to 10 hp if ported correctly across the graph. but your not doing bad with the setup you have.

Sounds like i may need to upgrade my intake. I have bought a true dual 3" xpipe + catback and plan to get rid of the dual/dual setup. Pretty sure that thing is robbing some power as well.
