Good day! Sorry if there have been posts like this before, but my question is it worth it to put a programmable ecu in stock abf? Main concern of mine is that I want to have more control of abf engine, I believe that with a programmable ecu I could map it to work perfectly. Is it possible to get any power gain? What kind of ecu's should I be looking for? How expensive are they? How much do I have to modify the loom to the aftermarket ecu?
