Transmission tune for 2003 Silverado??

Hello all,

Does anyone have a good transmission setup for a 4L80E in a 2003 2500HD Silverado. I have attached my current tune file, the car just seems all over the place, I dont really think anything is right including the engine tune...

The car details are:
2003 Silverado 2500HD
running liquid injection LPG setup (JTG)


I need to take the car in to get the tune looked at, but that probably wont fix the transmission side so asking the knowledgeable forum guys here...

Thanks a lot
Lee

Set Throttle Kickdown tables to 100% everywhere.

Use Torque Reduction upshift tables to control shift feel (firm).

If engine tune is not correct, then you must get the VE and MAF tables correct to avoid commanding under-pressure to the transmission.
