Don't go with any ECU upgrade that involves soldering in a chip. That is way outdated. All the major ECU tuners already mentioned simply upgrade the software. I went with Evoms but the others mentioned are probably just as good. Locality was a big reason for me with Sharkwerks right in my area. I have had a nice power upgrade and no issues whatsoever.

 

I would not use them. When I bought my car that's the tune it had. IMO it was a poor tune that I got rid of as fast as I could.

 

I'd never do an Upsolute tune. My car had one on it when I bought it... I switched to a UMW tune and the change was night and day... No comparison, and the upsolute is GARBAGE... I deleted my upsolute tune and LOST money and was happy to get rid of it... It's that bad in comparison!

The ones mentioned are quality tuners. I have EPL and Tony and the crew have taken good care of me and have great customer service!
