I guess Ill order the BMS DCI tonight and then the downpipes monday
Did you install the downpipes yourself? If so how long did it take and were you on stands while laying on your back or did you have it up on a lift
you don't need downpipes or a DCI to run map 2, but a 30% ethanol mix is needed to make it run properly.
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
