5 /5 Jake Benjamin: I have known Tom for years and he always does great work. I had my E55 in the other day and Tom made sure my car left in way better shape than Ilit came in. I ordered an aftermarket looped fuel rail and Tom was able to go get his thing dialed just right. He also went a step beyond and reset the transmission shifting adaptations for me since I mentioned in passing I thought it shifted a little funky. After the reset the car runs amazing and there was no charge for the computer scan. So awesome!
