Revo currently doing discount on their mapping. I'm looking to remap my 1.4TFSI. I have a couple of questions which some experience members might be able to advise. With Revo ECU remapping, will the dealers notice this when it comes in for a service? Can this be reflashed to stock if needed? What other big tuning companies would you recommend? At the moment I'm just trying to find out the pros and cons of each. I need to make a decision as the Revo discount is finishing at the end of the 2nd week.
