Hi,
Hoping someone can point me in the right direction. I have a 2006 GT 5 speed. I've installed undrive pulleys, a K&N CAI, BBK shorty headers, BBK throttle body, FlowMaster American Thunder mufflers.
When the engine is cold, it shifts fine; that is when I step on the clutch and let off the gas the RPM's drop as they should. When the engine gets to operating temp, the RPM's do not drop and sometimes increase a couple of 100 when I step on the clutch to shift. I took it to the Ford dealer, they said it had to be tuned and they could not do it. The dealer suggested Coastal Dyno in Tampa, but it looks like they are closed. Any ideas?
Thanks!!![]()
