Sometimes I'll be cruising along at 60mph, punch it, can get maybe .3 KR. Other times I'll punch it can get a moment of insane KR upwards of 12 points!
When this happens I can hear the engine hesitate for a split second as if I tapped the gas once, then floored it a second time, when in reality I just floored it from the get-go.
This has gonna be KR or something is banging. I'm beginning to suspect that oversize waterpump pulley I have is hitting the really close motor mount so I'm gonna get a lightweight stock sized one for the time being, but any other ideas what could cause this? Yes recently I did put in the 3.2" to test her out, but I can't see how going from 3.3 to 3.2 would cause speratic KR spikes.
