They claim to be one of the best tuners in the country. On their site, I need to get a link to their site, they claim to have gotten a couple of heavier Mercedes into the 11's and they do custom exhaust and more. Thanks, mark

I need somebody to do the 178mm crank pulley and Rob's PSK. I have my stock pulley turned to 70mm and will run that with the 178. I also have a PLXdevices wideband to install. Last is the fuel pump/filter/adjustable regulator. Chuk, if you see this and are still interested in helping I think I gave you info on what I would pay, mark
