Has a cam maybe??
I get it home and pull the tune and compare it to a stock one pulled from HPTuners. No doubt it has been tuned. Am i screwed out of my warranty??
Also I'm wondering if this still has a cam in it. Take a look at the timing for high and low octane.
Not too sure if it would make a difference being a Z51 or not though.
Can someone take a look and tell me what you think please?
Thanks
