Hey all,

Just picked up a cortex tuner for my truck and it doesn't feel like 25hp and 25lbs of torque what superchips claim.

I tuned it for 87 octane cause the numbers are just as good as the 91 or 93

I really thought it would have more jam then it does but it doesn't... I also have a airraid intake.

Am I missing something because of my cai? Does anyone have this for the 12 or 11 5.0?

I have also heard good things about 5star?
