I have a 2014 gmc sierra with whipple supercharger, i locally tuned the car but since then my plugs are running out and the car missfires while hptuners doesnt show any knock at wot!

I returned stock plugs and it seems better a bit with miss fires however whipple doesnt recommend them, what solution can i do?

 

Try tightening the gap a little

 

[QUOTE=Last Call;5286138]I don't think you need that bracket, you can make one for $40-50 if you have access to a sawzall, grinder, drill, and tap/die set. The only negative side to this as that the hose is in the belt path.

I've had it set up like this for about a year, no belt slip or other issues.

The other option is convert to 2010 and up Camaro accessories.

I have a lmg 5.3 with 2.9 Whipple. Is there a bracket I can buy to clear the bypass actuator. I’ve been having hell eating alternators etc. used the BD10 lsx innovations spacer -3 belt line. But need another option.
