BS3 vs 3 BAR factory computer
He can chime in with more specifics...
I ran just as fast on a stock PCM, but with an add-on 2 step and injector driver there was just too many wires for me. Plus the closed loop wideband correction is nice if you are changing a lot of things around and want to spend tome racing the car and not staring at a laptop. The internal data logger is nice as well, its amazing how many frames it captures on a pass.
But its not for everyone, as far as ultimate power as long as the spark doesnt blow out and both have the perfect tune the BS3 wont make more power than a stock PCM. I do know I can run a way colder plug without misfiring so its possible the BS3 has a hotter spark but I dont know for sure. Naturally with a 98 you are limited in what you can do as well.
