When is it time to upgrade your injectors?
I am rebuilding my motor and was going with aftermarket heads,cam and new intake. Would I need to get bigger injectors now or just get them cleaned by TPIS? If I need to upgrade what size should I get?

Ported Plenum,Hypertech Air Foil,Ram Air kit,SLP headers,AFPR,80series flowmaster and MAF screens removed.

You have an APDR already installed, so for a little bit of money(*$200), you could upgrade to the SVO injectors. Or you could clean and balance the ones you have. Id upgrade, thta way if you mod more in the future the fuel will be there.

Let us know what your combo will be and we can help you out more....
Sometimes people get to big of injectors and have to turn down the pressure on the AFPR. This causes less atomization.... Which can actually be worse for you than the smaller injectors....
