Just got a 1.8l previous owner said might need new injectors. Wondering what injectors I should get/ size. Also wondering what other little things can I change to see a little hp gains. Any ideas would be great.
Bigger better injectors cannot be ran well on the stock ecu, plus you don't need any extra fuel. You will hurt performance. Anything performance related that links to the ecu cannot be done without a Standalone or various bandaids to trick the ECU.
