if you would want to change your injectors anf fuel pump and fuel regulator can you get more fuel into the motor without a stand alone ecu? i have an auto fd with a street port cat back gutted pre cat msd ignition. I get boost spikes next mod is a boost controller. I hit fuel cut alot so now when i race stangs and z28's i have to watch the boost guage real close i dont let it get past 11-12. last thing is it a boost spike or something else? it happenes almost everytime im under WOT.
again sometimes i get no boost at all that i think is a soleniod issue. but basically can you get more fuel into the engine with a bigger pump and injectors with out the ecu telling it to send more fuel. if not would the afc be something to look into are they any good ? trhanks brian

 

Adding fuel won't solve anything, you're going to still hit the fuel-cut anyway. The only way to prevent it is to get an aftermarket ecu -- search for automatic-compatible options, there's been dozens of threads about it.
