I wanted to share my Dyno results for anyone else out there with a 2009 GT who is curious.

I have a 2009 GT/CS with 100k miles, JLT cold air intake bama 93 octane racing tune

My Highest Dyno result on a Mustang Dyno was 291 RWHP.

The HP is right on the money but I would have expected about 302-305lbft of TQ. The Mustang dyno will often yield lower numbers than a Dynojet so no need to worry. Just use the same dyno again if you add any further mods so you can get a fair comparison.
