Crank HP? A tune alone will do it.

Thank you! It was fun working with that car. And I didn't know you scooped that up - Email me some pictures!

​​@spdracerut is right. Crank HP is a lot different than WHP (which most already know). A FBO and tuned GTS made 488whp on our dyno which we found reads lower than most. That being said, I would be willing to bet that same car would make more than 500whp on another dyno - or if you ran it in standard correction (we only run in SAE).

I have a GIAC ECU tune through my dealer on my 991.2 GTS and the HP and torque increases are significant and very noticeable.
I chose to go through my dealer to (hopefully) avoid potential warranty issues.
