I have both... as soon as I get my transmission it's BOMBS AWAY! Which one would you choose? If I ad nothing else to the mix, which one would you choose? I have access to a SuperChips tuner... I also have access to an Edge EZ, possible stack? I've heard it's hard to beat the PM3/SMARTY stack, but the funds are a little short for that right now (i've also heard about some "shudder" problems?). Later down the road I hope to get a SMARTY if for nothing else to have the speedo correction if I don't pick up the SuperChips. OR... ... . should I sell 'em both and get the JUICE so I don't have to buy seperate gauges??? Truck is an 02 QC/LB/4X4 non-HO with auto and will aslo be getting a fuel system up-grade, 5" exhaust, intake, and turbo up-grade... . gimme all your opnions-good,bad,or ugly... THANKS!!!
