I'm not planning on making a lot of changes but would like to get a little improvement in Idle , MPG and a small amount of pep out of my 2.3 . So far all I've done is a Speedway header and full 2 1/2" exhaust . Only plans aside from maintenance is underdrive pully's and CAI . If I can upgrade my 21 year old injectors , knowing which way to go now would be a good thing . I thought of Bosch 14lb or 17lb . Some say stock is 14 , others say 15 . Can't be much of a difference . The question is will 17lb injectors help or will it not matter as long as they are newer , better inj . Ford Focus injectors are 17lb Bosch . You can get remanufactured and flow matched 14lb fuel injectors for about $70 or un-tested 17lb Focus ones for $20-$50 used . In the end I may get it tuned on a Dyno if I don't procrastinate as usual . Any thoughts ?
