          So far, no CEL and the car runs better and seems faster. Thanks!

          These guys are the best and know what they are doing. I was sceptical at first of doing the remote tuning but after some tweaking due to issues on my end they helped me correct it and the car runs super nice. Max option is 5 star but they deserve 10.
