Just trying to see what results folks have had on these two cal's. Or if anyone can recommend another cal for VXCF4. Tried the new ones before - not going back down that road.

What kind of mileage,power,other problems,etc. did you get if you happened to be using or have used one of these cals.

Any input is appreciated

I haven't tried the 8r10, but I have used the 8r14 and the 8r17 crom that they sent me. The 8r17 had many surges and the tranny shifted very hard. I'm currently using 8r20 and the power is much smoother, and the MPG have increased (an average of 1-1.5).
