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

I have tried more than 10 times to upload the HPT file but cant

You'll have to email it to whomever would like to work on it. Your converter should not grind. There's something wrong with it if you can hear it grind.

its new less than 300 kms on it

Make sure shift lock is disabled in the tune.

Make sure it will not apply in 2nd - you could do this for 3rd also

Then set it to apply at whatever speed you like in 4th all the way until about 60% tp then set it to not apply past that tp%

The third release should scale up from say 25 ish all the way to 60 ish at 100% tp The fourth Release start at 30 ish and scale to 60 ish at 100% tp

If it still grinds after this I would say something is wrong with the converter, boost valve, etc..
