Re: questions about ecu tuning. clueless.
Most likely a air/fuel controller should be enough, if you really want to be sure you could go with a greddy e-manage but your only true performance mods being hindered are the intake,headers,and exhaust which should be hurt by too much by the stock ecu's. i would still highly reccomend a air-fuel controller just to make sure you don't run too lean or rich with the new amount of air coming in . Thats my suggestion but i'm new to the 3s, used to the bulletproof 46g3.
