I've done a few small things in the last few weeks. Going thru data logs there is a little more heat for the intake air temps. So the only next upgrade for that is a varimax coolant pump, this is used on the zl1 and a lightning trucks. Seems to make my temps recover a whole lot faster and not break 130 degrees. The hose routing was changed so there are no bends and smooth curves. Also i had under load and light on the pedal smoke out the tail pipes and a hesitation after that a ck engine light. Scanned and its low voltage to the bank 2 sensor 1 o2 sensor. Testing just that it worked till it got hot and then the #'s didn't bounce around they stopped. Swapped that out and its good to go. I bought a nitrogen charge kit for my coilovers, they weren't charged as high as they should. So i'll charge em up and go from there, if its not what i want i have softer springs and a bunch of valving sets i bought from a few different vendors. I have the valving wfo uses in their dmax kits and the valving pure peformance uses, currently i have what king suggested. Between the 3 the shim differance is about .010 which isn't much.
