Even though I'm a customer, I try to remain objective when talk about him or any other tuners, he really is spectacular to work with. I always get tune updates within a very short time of sending him my data log, today I sent him two separate runs since I was able to get them in, one was later in the day so I thought he might not get to it right away but hell to the now, revised tune was in my email box before I was done grocery shopping. Car's turning in to a real asskicker with his tunes too.
