Soo i have a em1 and i want to get more power and im thinking about chipping it but idk what i want to do, people are saying you can use a p28 ecu and chip it, idk why they say that are there any other methods to get gains, what ecu or programs would be best

Definitely don't go buy a 'spoon' chip or something like that on eBay. It's just a whole lot of nothing.
