i got a 97 hatch ls turbo semi built! It spits and sputters when i give it full throtle. It has an hondata ecu and boost controler and not to sure how it all works. Dont know if its all out of wack or what... The guy i bought it from says that it has 750cc injectors! It will not take full throtle when so it just studders and backfires? Someone tell me whats up!!!

 

try a richer gas or like octane booter. i no someone that had this problem and he put a throttle body spacein and the problem stopped

 

RUN 93 OCTANE!!!! nothing but 93. and check all ur vacuum lines.

 

its a turbo ls.. it has huge injectors and a hondata ecu.. well to be honest the stock fuel system (yes even with 750cc injectors whoch makes it worse) cuts out around ehh 275 whp.. especially if it isnt tuned right.. no it could be the fuel system cutting out.. try turning the boost down a few psi and see if it still sputters
