Hey guys the mods on my car are on the bottom. When I let off the gas it pops out the exhaust. A guy told me I'm prolly running lean with the mass air and throttle body on. He suggested I up the fuel injectors by one step, without having to go into a fuel management system. Can any of you recommend a fuel injector size and how hard the install would be? I looked over it myself seems like a few bolts just don't want some hidden hinges.

 

I have a VERY hard time believing that with the mods that you have that you are running lean. I have PI heads, NOS, Exhaust, ect. and I am still running 19lb injectors.
