The solution that has been previously mentioned from a couple sources is the flash tune (here in the US is done by ACM in Florida I believe) which requires the car or the ECU. A couple people have done these and I would be interested in a long term review.

Member skinrock did the Gintani tune but I'm not sure if that is a piggy or flash. Maybe skinrock can let us know more details and how it's working out long term.

I pretty much got the first flash tune (that I know of in FL) it was not done by ACM and I dont ever recall ACM even tuning one.. nevertheless my flash was done by Velos in Miami and they dyno the car as well

Thx i was clearly confused haha.

So can you tell us how many tuned miles and whether you have experienced any issues? Also any dyno numbers before/after or any performance numbers with the tune?

Yeah sure, close to 5k miles no issues what so ever. Yes Velos did dyno the car as it was one of my requirements I have to look for the pics

: but the power is most certainly noticeable

Thanks, once I get the 2nd ECU, I will contact the tuners. If I lived close to one the tuning vendors I would have no problem just having them tune the car with the existing ECU.
