Spartan Tunes

Hi guys.
I have been running spartan gen econ tune as my DD for about a year now.
it seem to be the only tune that will shift out of cruse, and OD without a hard jerk. I have tried the stock plus, the MSE, and all the tow programs with the same hard jerk coming out of OD when in cruse. Has anyone else had this problem?

Thanks

I know when I have loaded the ASE,MSE or the hybrid race into my truck they all jerk when I hit the brake to come out of cruise not sure why either.

what i do to avoid this is when i'm in cruise control and want to turn it off i accelerate with the pedal up a couple mph and then push off on the cc

Trust me, this is not confined to just the Spartan tunes. My Diablo tuner did the same thing coming out of cruise.

So do you think this is doing any harm to the trans?

I run the MSE for my daily driver as well and it does buck real quick when I brake out of cruise. I have run it for over a year and not seen any damage, but this is a question to think about, I would like to know what the tech's say.
