I was having a issues on on running warm I replaced clutch fan runs cool again but it's been doing for awhile I think it's has something to do with ignition. Because between 2500-3500 rpm under half- heavy throttle it stubbles/ hesitates just doesn't wanna go but if I stay in it some times it will just snap of it boost kicks an it goes??? Checked for codes counting 5 slow 5 fast for no malfunction. I'm do it again tomorrow depending on the feedback I get. Plus I read something about the ptu the old style that I have was recalled. Cause they get hot an die I dkif this could be the problem. I also have the jim wolf technology ecu an I'm only on stock boost not too sure what spark plugs I'm running Bosch platinum once I changed the from the stock .044 to .035 that seemed to help. Also I'm running a lil rich at idle. Other than the hesitating it runs good.
