went tune my car today, I had a pfc in and a profac B spec II. tuner is reliable so I'd think it's more of the profac's fault, just wodnering if anyone ahd the same problem
started with standard factory .7 bar boost when the profac is instaled, tried to get boost up to .9 bar...however whenever pressure hits .9 barm a/f ratio droped went lean and the boost drop as well
....could not stabilise the boost.....tuner been trying to fix the problem all day, invite another mechanics in and still does not work...
somehow, I don't understand how, now I end up only with 150rwhp instead...of the initial 200rwhp (approx)..on 0.37 bar at most, reading from the profac display.... so I went slower after tuning ><
wonder if anyone had the same problem with profacs....and if anyone know how to fix this...
