I installed the Denso plugs last weekend and finished the mod lists this weekend. I installed the JL 3lb lower, factory tech valve body (also made several other mods while I was in there), JDM boost bypass, JDM oil breather cap, performed the boost actuator mod, 2" rear drop shackles, filled the trans with Mobil 1 ATF, and installed the reprogrammed superchip. I installed all the engine mods first and took it for a road test. I thought the trans was going to fall out of the truck with the added power. Put the valve body in and all was awesome! Definatly quicker than before, chirps the tires ONLY at WOT shifts. Only problem I noticed was after a sustained high speed 130mph+ for about a mile, I let off then climbed a good size hill and heard some pinging. Drove it today and didin't hear ANY pinging after I added 5 gallons of 93 oct. gas. (the temp was below freezing last night) I'll have to keep an ear out for anymore noise. Now I need traction bars, and a cat back exhaust.
