350 TBI Injectors

[76Blue_Beast]

Hello Guys,

I have a 91 suburban 1/2 ton and was wondering if changing my injectors would help out with power? I'm looking for small things to change to pull power out of the motor. It is a create motor with hooker headers, custom full exhaust and upgraded k&n filter. I just put 4:56 gears in the rear and saving for the front to be done. If you do injectors, do you need to change other things? Would under pulleys be something to do at home (like easy diy )?

Thanks,

Ken
