hey i still have my stock 22lb fuel injectors, in my 93 z 28
im wondeirng what size to get. and whats too, big?, ive heard that anything over 24 and you have to mess with the computer. or for me get a programmed chip

my mods bbk shorties, 1.6rr. Cai, 3" cat back, pulleys. msd coil, ram clutch, aluminum drive shaft. low tep theremo, hypertech chip, Lca's. sfc's, 4:10 gears, pro 5.0, lowerd 1.25" .

 

With the lack of mod's you have don't waste your time. You would be more productive to change your regulator and up the pressure maybe 2 psi. Be sure the things are cleaned right. That helps quite a bit.

By the way the Aeromotive regulator that is being shipped is not the one in the picture and it does not fit correctly. They suggested to me to tie wrap it. If you can believe it. Probably a good unit but search for someone elses if you're gona buy one.

 

As stated above you do not need to go with a bigger injector. However I would highly recommend getting an Ajustable Fuel Pressure Regulator. I picked up 10 rwhp and 17 rwtq with this mod. The Aeromotive AFPR is definetly a nice piece but in my opinion a waste of money. I was suggest going with a Hypertech.
