But yes, use map 1 if your stock with just 93 octane. Map 5 will normally auto-adjust to near or below map 1 levels, depending on how your car runs. E85 will allow you to run more boost without running into potentially harmful timing drops and ignition corrections
So if I did have downpipes and DCI then I wouldnt need a E85 mix to run map 2?
I have almost 1/2 tank of 93 right now. Say I go to 3/4 with 93 octane and then put 1/4 E85 in. Should I run map 2 or map 5?
