    No because even a stuck open stock one is not making the car run as cold as a 160. And I run a 160 in every thing I drive with no issue. Im trying out some thing new in the 08v but it might not work when it gets colder hear in pa but right now it's great. Runing very very cool.

    Oh yeah tim. My brother told me that the car was running rich when he was picking up the pulley, headers, throttle body and heat exchanger.

    I changed the parameters for my throttle body and took some fuel out of the low MAF chart because I saw it was running really rich. We didn't do any street tuning at all.

    How long has it been running like that? My throttle body does not require changing the MAF chart so that is not the cause in case anyone was wondering.

    Another Mr. Gasket 160* here. One thing to make sure of is that you have the right flash in your PCM though. It should be around here with a search. If you don't, you may trip a DTC.
