Superchips 1715 and 6# lower?
I've read that the HP4 program was meant for just a 4lb lower pully.
But on the Superchips website, they say up to 6lb lower.
Is the 6lb pully safe? Does anyone run that setup??
FRom the site:
Lightning and Harley Davidson pickups factory equiped with a Supercharger have a Perf/Tow program, High Performance program and an HP4 High Performance program. The HP4 High Performance Program requires a maximum 6 Lb boost increase, achieved by the installation of a lower pulley supplied by others.

I ran the 1715 HP4 with a 4lber for a short time and she would ping on me with 93 octane...
I had the a/f checked on a dyno and it was running lean at WOT, like in the 13's....
I would get the SCT 9100 or predator so you can get custom tunes...
