Ok i ve change my gear for a 3.73 and i bought a hypertech power programmer(really cheap) so i can recalibrate my speedometer.

I got a 160 thermostat so i also install the program for the fan to start earlier.

At the same time ive install the power program that give a couples of hp and pound of torque.But i ve read in the instruction that the program was set for 92 octane fuel.

Here in quebec city we only have 91 octane available.Is there any problem to run the program with 1 octane less ???

Thank you

 

1 octane shouldnt make a difference. I run 93 with the tuning because thats all i can get here.

 

Thank you
