i've just ordered a cobb intake and cobb inlet pipe, would you recomend the stage 1-SF 93oct, the maps only talk regulation around the intake, downpipe, intercooler, or exhaust, not about the inlets (especially since its a cobb part), i've heard speeds spiking to 20 with just those two mods, also, should i be looking into a BPV as my next mod, i plan on staying street legal and as least obnoxious as i can, so forge is out of the question, when the knob is set correctly, would you say the turbosmart has the best chance of performing quietly and emissions legal? (to me the forge sounds obnoxious) i'd rather sound like an 18wheeler. the hks also sounds a little too rice for me, but will it perform better with stage1sf93?
