Morgan, Looking in more details, you said you copied the stock CTS-V oncoming/offgoing pressure preset for the 3-4sp ?, but I think by mistake you zeroed out the oncoming pressure preset values in your tune compared to a 09 CTS-V, can you double check it ?
I'm preparing the file i'll be loading in my car. I guess i would be using all the oncoming volume preset values from the the CTS-V as well, i compared your last file vs a CTS-V and they're the same values.
I'll keep everything else i have the same in the test, the only difference would be the Oncoming/offgoing preset for the 3-4 sp shift, and all oncoming volume preset values, which would be coming from the CTS-V like you did.
