another goddamn exhaust thread (searched)
 

Im looking into a turbo back cause the custom job that came on my car sounds awful, and has a small leak.
anyway
I already have an fcd
I'm wondering if once I get it, would you reccomend to up the injector size and get everything tuned? Just thinking it make everything run a lot more smoothly..
but if you guys dont think either the inectors, tune, or both are necessary I'd like to know why.
thanks in advance

you will be fine if you just upgrade to a walbro fuel pump and rewire it. do you have an intake (and/or TID) as well?

you can run 10-11psi on a stock motor/injectors with a walbro rewired. going over that is where it starts to get risky.

I've got intake and bov right now.
stock dp
so you suggest a walbro 255 to go along with the turbo back?

With stock ecu, and a FCD, larger secondary injectors would be recommended so the upgraded pump can be utilized. Just do a check on voltage to the pump when under power, and if within specs a rewire wouldn't be needed. Also, a FD pump makes a nice upgrade, and an easy install using the FC sock.
