The Procal adjusted for my gears and tire size so the speedo/odometer reads correctly.

I really wanted to try a tuner, but I have a 2011 and they haven't "cracked" the computer yet so there isn't a tuner available.

Ahh ok... so the procal is just adjusting the speedo but not "tuning" so your not getting the possible benefit of a tune, which may help mpgs further than just the speedo recalibration.

Am I on the right track?

Yes you are. A tuner gives performance benefits by modifiying the fuel and ignition maps. The ProCal corrects the speedo/odometer, which is important to me since I have an automatic. If the computer wasn't corrected for the gears and tire size, the shift points of my transmission would be off.

Thanks...

So hopefully a tuner will help altogether as it will do right for the speedo, tranny shifts, and fuel ignition maps, thus all helping mpgs become more accurate (via the dash) and hopefully better in terms of actual fuel economy with more mpgs.
