Kevin, I have a Unichip that I bought in December (new) from Unichip NA. It came with a low boost and high boost tune that is changeable by flipping a toggle-type switch. I prefer the high boost tune. I thought that the car was great until I installed the Unichip.............but, the Unichip really woke up the engine and made a tremendous difference. I have never driven or ridden in an Abarth with the EC/HPSI tunes so I can't compare the tunes but I'm very happy with the tune that I'm running. I'm happy to see that Unichip is developing more tunes but I'm really interested in the throttle booster software that they're going to offer in the Q4. I used to have a Go Pedal but it made the throttle too twitchy with the Unichip tune so the throttle booster would replace the sensitivity in the throttle that I used to have with the Go Pedal. It will be very interesting to see how the new tunes work. I do not want a handheld tuner (used to own one for another vehicle) so Unichip is my choice for more performance on my Abarth.
