hey guys. Im looking at spending about 1.6k-2k on an engine mod. Im trying to work out which would be the best gain for me so any help would be appreciated. Im looking at either an ecu or fmic and cold air intake.
In that price range what sorta ecu would i be able to get.
Was told i might be able to squeeze a link system. Are they a piggyback or replacement.
Or would goin fmic and cold air intake be better option for now.
not looking for an 12 sec car or nothing just a bit more fun.
