I have done all three with Eurocharged. First, I sent my unit to them with my list of mods. Two days later it was returned and I was running strong. Second, I added more mods so I made the trip to Houston and had a dyno tune (which is a really cool experience) and had some fun with the Houston Crossfire crowd. Third, added even more mods and did the remote tune. I invested in a Zeitronix setup to get AFR and other outputs which allowed me to send files to both EC and NW for their feedback. After a few file uploads and the addition of an SL55 fuel pump, I was back in business. I was really impressed with the remote tune experience with EC and their commitment to get my setup right. I purchased the Zeitronix because my mods were getting me to a point that AFR's could be getting dangerously high...glad I did because I was running lean.

This is just my experience obviously so I wanted to share. I have heard good things about Inmotion as well. At the time, EC was closer and I heard good things about them as well. Good luck.
