I just spent the afternoon at RPi getting my ECU re-flashed to the new RPi/ESS tune 
The old tune felt jarring under wide open throttle. During acceleration the car would jolt forward violently. Towards red line, the car felt like the power would taper off. With the RPi/ESS tune acceleration is much more uniform. When the car reaches 5k RPM the car pulls heavily! It almost felt like i have a 25lbs shot of nitrous!!! I immediately noticed a difference between the two tunes. I love it 
Thank you Eloy@RPi and the boys at ESS for such a great product. I highly recommend anyone contemplating on ECU re-flash to give the RPi/ESS tune a try.

if you wanted to do the RPi/ESS reflash, just next day RPi your ECU. I believe the turn around is one day, so you'll have it back within 2-3 days.
I wish I was little bit taller,
I wish I was a baller
I wish I had a girl who looked good
I would call her
I wish I had a rabbit in a hat with a bat
and a '64 Impala
who me?
no way!
