The JB4 tuner installs between your car's sensors and its DME/ECU (computer) and manipulates vehicle performance through these connections making your vehicle much faster. The JB4 is a plug and play tune available for turbocharged vehicles. While Jody is definately one of the top programers in the country, he was not the first.1 Series (N54) E81 / E82 / E87 / E88 / 1M Obviously the TS Performance dealers use Dennis Perry's programing and DP-Tuner's dealers use Jody's programing. TS Performance has their dealer base, DP-Tuner has their dealer base and so on. There is a handful of other custom tuners and a boatload of resellers of the different tuners. I do believe that Dennis Perry does the programing for Bob at Dieselsite (not 100%) and these programs were built for Bob.

Dennis is the manufacturer of the chips you see for sell, with the exception of Superchips who still makes their own.īill with Diesel Power went to work for Edge Products and dissolved the company and Jody started DP-Tuner and Bill and Jody reached an agreement to have Jody continue to provide service to his dealers (post edited I was wrong about Bill selling his business) and some of us have surmised that the DP stands for Diane's Programing /ubbthreads/images/graemlins/blush.gifīob sells the same 6 position chip that Dennis sells at ITP Diesel, that Jody sells, that Ts Performance sells and so on, only they have different programing on them. Steve still runs his business TTS Performance, Bill did some tuning for Superchips and then went out on his own with Diesel Power chips.ĭennis Perry started TS performance back then sometime as well. Along time ago in a galaxy far, far away, Steve Cole was prolly one of the first 'custom' tuners.
