Anyone wo tuned a Lockup converter please help
I installed the PI 3600 Stall converter on my 08 silverado and Now im stuck with the tuning thing I drove the car for 2 weeks without tuning and had no problems at all until I installed the cam and Took the car to my tuner we tuned it for the cam but when we came to the converter thing we got confused . We raised the TCC speed in all gear to 400kph and it became worse I apply Full throttle The rpm goes and stops then it goes again and stops and when I'm under the converter speed the car will change sound and you can hear the converter grinding and it tries to lock.
Retrned the Gear setting to stock and still uner the stall speed the car wil change its sound and the converter will start grinding.
Please help
