I plan on installing 24lb Injectors on a stock 350 Cu In TPI 1989 Camaro engine, will there be any problems as far as the engine running too rich or Fouling The Spark Plugs Or With The Computer.

 

You will need to get the computer set for the new injector constant. Its a pretty easy job, if you have the right equipment but you can probably get this done cheap.

 

Found out stock injectors are 22lbs so the 24's should be ok with the new SLP runners that willl also be installed providing more airflow: http://www.fbodymotorsports.com/inc/pdetail?v=1&pid=965

 

You could just put an AFPR on there and set it to 48-50 psi. It does pretty much the same thing without having to burn a new chip only the extra pressure is a bit harder on the injectors.

 

I have a new BBK afpr in my garage that I dont need. If you want it for $30 let me know. Like they said, it is the easier way to go.

 

Give it time, the ecm should adjust for the added fuel, use a scanner, I think you'll that it will.

 

I'm running 24lbs one in my Iroc (LT1 injectors). Had Ford Motorsport 24lbs. in my GTA as well. You can get by without tuneing without the overly rich condition. As mentioned install an AFPR and turn the fuel pressure down to the 41-42lbs (stock is 45lbs)and you should be good to go.

Tuneing would be best but not absolutely needed yet.

 

Installed the new Holley 24# injectors with the SLP runners & a new fuel pressure regulator, car is running as smooth as new. Low end power is definitely improved.
