Spark plugs tell the story. For me (one baffel removed from stock, three 1/2" holes) I removed the bottom half of the snorkel and it was like cutting a dog loose from a chain. Plugs were fine, dealer even checked it out said it was fine. You may end up with pops on decel, that will require twisting the fuel air mix screws Dinqua has the fix for that in tech.
