Shifting was good also, 3-5 shift a little hard but it has been with other tunes as well. On a side note this tune shifts like the early version of the 310 and the how the 275 shifts I believe. Better for towing IMO.

The hard 3-5 shift is because of your Suncoast direct solenoid...its causing too much line pressure in conjunction with Spartan tuning and the Spartan TCM.

No, this is KEM's tune, no spartan tcm with this one. I realize that might be happening when I'm running Spartan tunes tho.
