Nismos car put down 139 whp and that is stock with anly the ECU. Stock 240s’s usually put down between 125 and 130 whp. I think for the fact that it has a slightly higher rev limiter and no speed cut it is worth it. ---

i am assuming that this ECU would be programmed to run off of stock injectors right? can i go any bigger without running too rich? or is the only way to put bigger injectors and have them work properly is to have the ecu re tuned? :? ---

would it not provide more fuel, and if you tune it right, would that not give you more power, boosted or not?? :lol: ---

with an N/A engine though, you can only force so much air into the intake naturally. Otherwise you jus have more fuel and maximum capacity air which I’m not sure exactly what amount that is but wouldn’t be enough to require bigger injectors. ---

Usualy with a stock engine if you lean it out it will put out a little more power. Most cars are tuned rich for safety from the factory.
