Hello, I'm still having an issue with KR, let me start by saying a bit about my car. I drive a 2005 GTP Comp G with 125000 miles. the car has Speed Daddy headers, 3" high flow cat, K&N Cold Air Intake, 3.6" SP Pulley, Overkill Tune, fresh Autolite 104 plugs and wires.
When I go wide open throttle I sometimes get over 9 degrees of KR at around 10 to 11 Psi of boost. (I'm scanning with the Torque app) the car still runs great and this happens in all weather conditions.
a few things that I think might be adding to my issue is the #4 coil terminal is rusted (I plan on replacing the coil when I can)
and the last owner welded in a 2" pipe to the front of the resonator where the down pipe bolts on. I'm pretty sure my headers go from 3" down to 2 1/2" at the resonator so its not a smooth flow of air.
I'm not sure if my exhaust issue is enough to cause KR or not but I kind of think the rusted coil terminal is.
also, the overkill tune is set for a 180 degree thermostat but I am still running the stock one. (I'm also planning on replacing the thermostat soon)
oh one more thing, my transmission dip stick tube is touching the header, do you think I might be getting false KR??? thanks
