The Official Superchips Forum

I was reading to try to find dyno specs but had no luck! I have a cortex programmer and 5.3 my engine code is "J". this is my second programmer and im just curious! also i was was wondering when i program my truck with the performance file which setting gives the most power the "superchips" value or the highest setting? for example is it better to put the shift pressures on superchips value or the highest shift pressure? also hp wise is it realy true that you get more power from the 87 octane settings? where can i find both dyno results!

Thanks for all the help!

Welcome to Superchip's Forum!!

91 perf=18.5hp and 16ftlbs of torque at the wheels
91 tow=11.3hp and 10.5ftlbs
87 perf=17.5hp and 15.9ftlbs

On GM products the SC preset is in the middle of the scale.
