Hey guys, anybody do this mod? I have read a few articles now that say the best gains u can get on a stock s2k ap1 motor are not intake or exhaust or ecu but the fuel system, because that has the most area for improvement...now if this is true how much hp am I looking to gain by upgrading the fuel injectors to aftermarket like spoon...? 2-5hp?

 

Try it and let us know. ecu controlls the parameters of the engine including the injectors. not likley, but go for it and let us know the results.

 

I would say that having an ECU installed rather than changing the injectors would be the better idea. Having any modifications without a remap won't gain the most the engine can give... I think most people add a return system from the fuel line but i am not sure... heard it through the grape vine...
