I have read countless forums trying to figure out what I should do with my car, at this point I have a 42 draft DP to a cat back magnaflow all catless. im looking to change the DV, but other than that I don't plan on doing any other performance mods! WHAT do I do about this narrow band ECU tune it with eurodyne? or swap the ECU for a AWP LP or PL wide band, with the unitronic plug and play with o2? I Just want to pull out some horses and increased gas mileage all keeping the car safe from grenading
