I love the way this tune shifts and drives compared to the TCM race tune that was n this truck. Only problem since then is durign shifts it seems like the tranny almost slips and the RPMS bump up then down during shifts. This only happens wide open and about half throttle. The old TCM tune did not do it. What tables can I compare for differences? I am a begginer EFI live tuner so be easy.

I suggest you log the tune and look to see if it is defueling on the shifts or fueling through the shifts.

If the '01 TCM was from a stock truck the taps are probably not ready for the extra power.

You can preset the TAPS with a TECH II or with EFI-LIVE.

I have had this tune running about 2 months now. Is this enough time for the taps to learn the change? I also reset taps today. I was looking to see if my 1st few 01 TCM tunes were doing this.

fueling through the shifts.

I'm guessing this is accurate ;)

Which 01 trans tune are you running? I loaded the tune bobo uploaded on the library not the "performance tune" someone else did.
