Engine 1989 turbo mustang

[89turbomustang]

Hi new here. Just pick up a 1989 mustang with a f303 cam with rockers Ford racing aluminum heads cobra intake manifold with turbonetics turned down to around 10 to 12 psi currently running 26lbs injectors seems like I have a lot off wasted fuel. Wondering if I should down size the injectors any help will be appreciated thanks

26 lb injectors?? What color are they?

Using 26 lb injectors with stock 39 PSI pressure won't provide enough fuel for a turbo pushing 10-12 PSI boost. What fuel pressure are you running and what size fuel pimp do you have?

Walbro 255 and if you upgraded your injectors you'll need to re-calibrate or upgrade your mass air meter to match the injectors.
