I have a 91 camaro 3.1 and i've read the post about changing the stock injectors with ford 2.9's. I know that using the ford one's would increase my performance but my main concern is gas mileage. I'm trying to decide if i should by the ford's or just get stock replacements. Would my gas mileage get a little worse with the ford's?

 

Your fuel milage should remain the same as the O2 sensor and blcok learn function will keep your part throttle fuel delivery in check. You'll gain a little performance from the slightly larger injectors, but nothing to really notice. I would just go with stock replacments for ease of future work. I know there will be people that disagree with this, but that's just my
