I have an open air intake and a flowmaster exhaust with no cat. So i know the motor is getting more air, so i'm assuming its gonna need more fuel. Its an 89 305 with TBI. What injectors are in there now and what would you reccomend for aftermarket injectors. Also, is there a truely precise may to figure out what injectors you really need or is this stuff just an educated guess? Thank

im pretty sure the stock injectors will be able to keep up. wut about getting a Adjustable Fuel Pressure Regulator, if they will work on TBI's

Check out my sig. After my mods my car was running too lean. I just popped a couple of stock 350 injectors in there and increased my power substantially. No more lean and no more knock counts. Since the stock 350 injectors are only about 10% larger than 305 I didn't mess with computer chip and everything seems fine. No gas mileage changes or anything like that.

I doubt it.
