Here is the situation...
Was planning on going to XS engineering in So Cal to get my PFC w/commander tuned to meet my new mods. But then I was giving it some thought today and I dont feel like spending the money if not necessary.
I know PFC is tuned for all bolt ons and 12 psi. And that all sounds gravy for me but here are my Q's.
I have downpipe/midpipe and enfini y...is PFC tuned for that?
I have BNR stage 2 turbos...will that dick with my timing etc vs. stock turbos?
I have Greddy SMIC, will this need to be tuned in or not?
Also...have 1300cc injectors. I know PFC isnt tuned for that but know it is doable. I was wondering how hard it is to tune the PFC w/commander to the 1300cc injectors.
I have a 255lph fuel pump...does this need to be tuned in?
Full list of mods: 1300cc, 255lph fuel pump, greddy smic, bnr 2's, dp/mp, cb, act s/s clutch, apexi intake, enfini y pipe...what I want to do is put in the PFC and leave base map except for the 1300cc injectors. Is this dangerous or a good idea? If it sounds good does anyone have the base map except for the 1300cc injectors that I can use? Thanks and please get back to me on this.
