i cant remeber the website i was reading, but i think i read that if you upgrade like the intake header and exhuast you have to upgrade the fuel pump because the engine will run lean. did i read it wrong and misunderstand ??

 

if you're running ona a 13bt, and you upgrade your intake and exhaust, you should upgrade your fuel pump also, because if you dont, you have a chance of running lean, detonating, and blowing your engine. www.aaroncake.net

 

aaroncake that's where it was i thought thats what it said

TRULY....... WORD

 

Ah, thats what I was looking for. I knew I was forgetting something. Also check out www.fc3spro.com. They have lots of good info an turbo fc's.

 

sweet the more info i can get the better

 

oh if i upgrade the fuel pump the injectors would have to be ugraded to right ?? ( i ment to put this on last night but fell asleep )

 

Not unless you have some form of aftermarket fuel control to trim those injectors.

 

well in that case i plan to either

a.) buy the A'PEXi PowerFC

or

b.)A'PEXi Super AFC

and i'm leaning more toward the power fc, but from what i read the fc's ecu is'nt that bad... so a piggy back might not be a bad idea... however i would have more controll with the power fc so what do you guys think ???

 

The power FC is not really suited to the FC. Especially the S4.

 

so then rolling with the super AFC piggy back would be more suitable ??

 

Either that or a real standalone.

 

Consider an RTEK. They are relatively inexpensive and will cover what you are looking to do.
