Hay bud, I have read a lot of your post and see that you are the one person that will be able to help me on what I am looking for. My car is an 2003 with a stg 1 comp and inj, 255 walbro fuel pump, APEX I 2 fuel controller, fm e2 turbo, and ported exh manifold. I ran this combo on the track just once, at only 18 psi. I know this turbo and set up has a bit more in it. What I am wondering is, how can I rescale the comp to run a 3bar and tip without running a DSP? Correct me if I wrong but, don't the tunners that are out right now only use the tunes that are in them when you are at WOT? I just want to have the option the tune my car from idle, to redline. is this possible? I still have my stock comp by the way.
