I was thinkin about upgrading my fuel injectors on my 98 gt.... I dont know too much about the topic so all info is appreciated, from the research ive done it seems that the stock ones are 21 lbs and cobras run 26 lbs. Im just wondering how muh power i can get out of upgrading them (ofocurse thats debatable) and also what other changes i have to expect , esp as far as compatabilitiy and reconfiguring..... Thank you

btw i have flow master cat back exahsut, and K&N FIPK CAI, and soo to have a mac prochamber H pipe. .....

Your stock injectors are 19lb and cobra's are 24lb.

You are no where near maxing out your stock injectors with the mods you listed so there is no reason to upgrade.

Once you do more to the car as far as PI headswap & cams or a supercharger, then you would need to look at swapping the injectors. For a headswap/cam car, you could pick up a set of used 24lb injectors fom a cobra and they would work well in the 300-340rwhp range, anything over that you could step up to the 30lb and be fine. Your 19's will be fine untill you reach 300 or so.
