Got it in I know now what all have said about the sound. It made a little bit of an increase as long as its not hot. I'm thinking thats just from how the iat hooks up. I did the temp mod on te iat by just putting a fixed 75 K resistor instead of the iat and it made a lot bigger difference I think that is the fix to peoples heat soak complains. Even when it was realy hot with that it took off fine. Pain in the butt cause I had three wrong parts but I still managed it.
