Leaving rpms alone and speed limiter alone as well. Getting rid of the cold start mess so it won't run like crap when it's cold. They are out of the Simon handheld tool but they offered to flash the car and give me the tool when it comes in. These guys are great that's why I always keep coming back. Customer service is great. I've been a customer here for years and years since the old E36 M3 days.
