Alright guys, whenever i gas it and the boost kicks in the engine seems to bog and it holds the car back and doesnt accelerate very well. It does almost everytime i kick it and it is bugging me! I have stock injectors, walbro intank pump, aem high volume rail, aem FPR, and an safc untuned. Would this fuel setup cause this? i have 450cc dsm injectors but i was gonna wait till the day of tuning to put these in because wouldnt it mess up the air fuel ratio? or do i need more fuel and this would solve it? thanks alot for any help!

 

Because you are not running an FMU. If you want to run the s-afc hack have it tuned and properly hooked up. Keep boosting and you're going to blow your motor.

 

i was running the vortech fmu and it still did it when i had that on.

 

check for wear on cap and rotor. replace wires and plugs. sounds like car isnt gettign spark.

 

i will check these....thanks

 

sounds more like a fuel problem because if he wasn't getting spark when he opened it up it would probably feel more like a skip or a rough running motor altho i was running 1 cylinder short and it felt just dead. Make sure the spark plug isint sparking into the block and not getting spark in the chamber.

 

alright i will check that too. thanks
