N55 Tuned!

Today we did our 1st N55. On the dyno. I'm still not happy with the gains, this is the 1st attempt at it. We still have a lot of work to do with the high rpm boost taper. Looks like we have to do more work with the boost control or else the turbos are just out of puff at high rpm at this altitude. I suspect it may be the latter as the wastegate duty cycle is pretty high to get that boost up top. Anyway, documented gains of 25kw & 80NM in the mid is a half-decent start I suppose.

Hi there, we can do both piggyback or flash tune. The choice is up to you. They both have their pro's & con's. The ECU tune we have to remove the ECU from the car & benchflash it, which is a tricky process. But we have already done & tested that process, but due to warranty concerns most customers do not want the ECU opened. Drop me a mail or call me & we can discuss the best route for your car.
