Okay, so i'm planning on some big mods over the summer (S2 intercooler, XP cam w/ 105 springs and double roller, Mototron 65 injectors (or is Lucas 42.5 enough) , larger TB and a sub 3" pulley *is there more supporting mods that i'm missing for about a 2.8" pulley if I have 0 KR?*) so my complete list of mods will include those along with pacesetters with hi flow cat and ubend, CAI and PCM, AL 104s and 180 tstat. This is where my question starts basically, I want to get the PCM now but I know I will have to reflash it when I get certain mods done, ie the cam and smaller pulley). So I just wanna know how hard it is to reflash and what i'm looking at for rewriting the .bin file. I really dont want to wait to get the PCM until I have everything because that won't be until like the middle or end of the summer. Is it hard to write proper values and tables or whatever?
