What am I gonna do? Seems like ever shop have their good reviews and bad reviews.

 

Should I just close my eyes and pick one?

 

I had a good experience at EFI when Chris was the tuner. Had them swap out factory turbo, IC and fuel pump and tune my WRX all in one visit. They were very professional. The charges were fair. The tune itself was perfect for me (270/310) at 40k miles, and the car has gone on to 100k trouble-free miles. Only hiccup was when a CEL came on day after I got back from their shop due to a busted O2 sensor. I suggested to Chris that it must have been damaged during some of the work at his shop, and he agreed to ship me a replacement OEM part at no charge.
