Awesome, another Callaway SC750.
I can recommend a software tune anyway, tune on my car was dogshit and was just a little above stock ZL1 power. Same was with another SC750 here in the forum I talked to.
Jannetty took care of the software and it runs perfect now at the advertised 760 HP.
Callaway tune has very rich fueling and uses advanced intake cam timing at high rpms.
I can promise at 760 HP, the main catalytic converters won't last long under track use.
