Switched out the Haltech piggyback system for the RENNSPORT ONE EVOMSit ecu upgrade - absolutely incredible!!! I'm not really too sure about the details as far as tuning specifics, but what I do know is it's a huge improvement, not only from stock, but from my old ECU which was already great.

Power is very strong from about 2500 all the way to redline, very consistent pull throughout the rev band. I was thoroughly impressed after test driving it.

Just wanted to say thanks to Justin at RennSport One! Keep an eye out for these guys - they're setting up to be a strong player in the exotic tuning market.

I can also vouch for Justin at Renn Sport one, he's taken great care of me and provided excellent support after the sale. Above and beyond! I'm looking to do the ECU upgrade next as well!
