Description
I do 6 different levels of STAGE 2 chips but I am just listing the one order.
Level1: stock 165 duration @ .050″ camshaft which I dont recommend and thus really dont sell any of but I am not changing the level order.
Level2: 180 duration @ .050″ camshaft which I don’t do many of but its available. example cam is a Summit Racing K1100 camshaft.
Level3: 190 duration @ .050″ camshaft which is what GM uses in the 1996+ trucks so its what should have come in the TBI engines from the factory.
Level4: 200 duration @ .050″ camshaft, this level performs poorly with stock chip as we are getting quite a bit more duration than stock and gearing needs to be considered for this level.
Level5 210 duration @ .050″ camshaft, I really dont recommend this much camshaft with TBI heads. You just lose too much low end for very little gain on the top.
Level6 218 duration @ .050″ and must be at LEAST a 112 LSA and really should plan on datalogging as this much cam is difficult to get to idle just right but does sound good but needs at least a 2000 rpm stall and good gearing for the size tire your running.
