so i got my s2k back from being supercharged at my shop everything running smoothly except im running really lean like a 13.5 and the guy said be careful, now when i got it tuned and dynoed and a/f test i was running straight off a test pipe no exhaust at all, however i just put a stock ap2 exhaust on would that fix the leanness of my s2k? cause im looking at the parts list for my v2 kit from vortech and there is nothing about injectors nothing on the whole thing lists injectors or even on the instruction manual says anything about installing injectors, so if the kit isnt suppose to come with injectors why would i be running so lean? would have putting an exhaust on fix it?

 

Do it right or don't do it at all. You need to upgrade your injectors, fuel pump, ecu and have it tuned. You're going to hurt your engine quick.

 

already have the fuel pump, looking at getting an emanage with 450cc injectors

 

450 cc would be to small in my opinion. Get bigger injectors so you don't have to buy them again.

 

13.5 is that wide open or at idle

 

The base VT fpr sucks ass. There is no adjustment to turn up fuel pressure which is what you need to do. Comptech has an adjustable rate fuel pressure regulator, id recommend picking up one of these, or sure... you could blow a few more thousand on injectors or stand alone if you feel the need, but its not necessary at all …and I think under the circumstances is lacking advice. Yes your exhaust will richen your afr up a little bit, but likely not enough to dip into the mid/high 12's which is where you need to be minimum at the stock 6-7psi boost.

 

Injector Dynamics 725cc FTW

 

oh another thing i forgot to mention im running a big bore throttle body from sos, if i were to change that to stock would that rich me up more?

 

Id725 and aem or get a comptech fmu and use stock injectors at stock 6psi

 

how much boost are you churning up? You drive an AP1...I would seriously upgrade your fuel system...like now. I would also suggest less commas and more periods.
