How will my car react to bigger injectors????

Well, I have to replace at least two of my fuel injectors. They are both pretty much dead. I figured, since the injectors have 90,000 miles on them, I may as well replace them all. Since I am replacing all of them, and I eventually may need bigger injectors if I ever buy a Super Ram, how will these bigger injectors affect my car's performance? Will it benefit (more power/fuel economy) or will it be hurt by adding these injectors? Also, what brand of injectors do you guys like, and where can I get them for a reasonable price? All of my mods are listed in the sig. Thanks in advance.

I've heard of some people having problems with codes when running 24 lb injectors unless your into burning proms.
I am going to get a set of Accel's. They make 23 lb injectors which supposedly causes no problems.
Talk to Rich @ www.cruzinperformance.com

the computer will just compensate for the bigger injectors by shortening the pulse width to the injectors. of course this is only in closed loop. in open loop, if you havent done quite a bit of breathing mods, you might run a bit rich.

90,000 miles and they're dead already?? My '86 TA has over 200,000 miles on it and the injectors are the originals from GM! Guess some people are just a little less lucky than others!!

I'm replacing my engine soon with a 350 and I'm putting LT1 24# injectors in mine! I got a steal of a deal on a complete set of LT1 injectors and I just recently sent them off to Rich at Cruzin Performance to have them cleaned an flow matched! Check out his site www.cruzinperformance.com .... for $80 he will clean the injectors and flow match them so that they flow better than they did from the factory... as well as installing new screens and o-rings, it's a good deal!
