Thanks for this - they look to be about 60 lb/ft lower than the rest in the Torque department.

Don't put too much stock in that - they use an extremely conservative Mustang dyno and always report numbers at the wheels, not to mention testing with 91. GIAC's real world results are always at or near top of class, especially if you run one of their more aggressive files which they don't often advertise.

APR is the best bang for your buck is38 tune IMO, it’s proven reliable roughly 360whp and what I run on my car.

FCP is a no brainer for the is38, who doesn’t want a lifetime warranty?

Not 100% on topic, but for arguments sake here you go as well

I agree with Jake. APR is a good choice. It’s really a good option if you are already tuned by them. The upgrade to the is38 tune is $250 for current APR customers. I’m running this tune and I love it. I’m not looking to make the most power possible. I just want a reliable tune that won’t kill the is38.
