I am Contemplating changing my turbo on my car but have been advised by a mechanic that has worked on rally cars to change my computer instead of changing my turbo ( better place to spend the money) I try to advise him that it is diffrent to rotary's, evo's,wrx's etc. But he still believes that with a stand alone computer I would be allot safer. Iam looking for 400rwkw in a bf phoon. I know with the old rotors I needed a 3d tuneable computer with cdi to stop the turbo blowing the spark out. But I can't imagine that a bf with to4z tuned right via a cappa flasher would cause any problems. Mayby if I was going all out, so what are peoples opinions have they had any problems with there flashed computer not being able to keep up? t
