Hi... I am thinking of buying a piggyback ECU controller for my 2000 Lancer Cedia. But I'm wondering if I can get them to work on the GDI engine since they have a higher compression rate. Which piggyback ecu controller is better? I'm looking for those around $300. I'm thinking of getting the Apexi AFC Neo. Does it fit in every car? About how much performance gain can I get from installing it? I can use it to configure my car for faster acceleration right?
