Just adding my .02, and I agree with others. The stock F23 Eurodyne tune works.. But just that. Doug (Frankenturbo) and Chris? (Eurodyne) both gave me pointers on what should be adjusted with the tune. Neither went out of their way to ensure my F23 tune was running optimal, but I didn't push it either.
Andy from (
tunemasestro.com) did work with me (I donated what I felt was fair, and he seemed genuinely thankful for the donation. I'm currently happy with the car/turbo.)
Nobody around me is familiar enough with Eurodyne to tune it, but I'm thinking about doing a dyno run or two and log it and provide Andy with the info for him to do his magic.
If I had to do it over and pick either COBB or Eurodyne, I would shop around more and see who provided the best support to either and go with that. If I couldn't find support with either, I would pick Eurodyne again because honestly I can't really fault it. Then again I haven't used COBB so take my opinion with a grain of salt.
//Eurodyne Customer Service
Just a note with Eurodyne, I've always had every email answered back. (plus) They seemed to never provide all the answers to the questions I asked (negative) But in the end I'm satisfied.(neutral) If you want to experience their +/- customer support, just send them email with any questions you may have and see how they reply. Then you can decide if it is good enough or not for you.
