So for those who have been following i was kicking around the idea of either selling the m5 and getting an e92 m3, or keeping her and going FI. So i decided to go with the ESS VT650 kit. Really can't beat the price at $4995. ordered the kit tuesday, they shipped it overnight and had it wednesday morning. been picking away at it over the last few days and finally got it buttoned up tonight. still have to route some wires and make a few adjustments but shes on there. software downloaded and uploaded flawlessly, pulled the read file in the early afternoon and had it back the same day. first start was smooth as silk, not a sputter, hiccup, or miss. only took her for a short ride tonight but all i can say is holy $hit!! wow what a transformation of the vehicle. cant wait till tomorrow to get some driving time in. would like to thank Roman and Mike at ESS for a smooth transaction and for fielding my numerous questions over the last couple days and being a relative pain in the *****. they are great people and are a pleasure to deal with, highly recommended.
