DSM injectors and the black box would be the best setup. bigger=better in this case. as far as emanage goes, you need the emanage, a support tool, and some cash to finance. my friend had a d17 with just a t25, 6 lbs boost. with the rsx injectors, he still managed to run lean, even at a 95% duty cycle. might have had something to do with him thinking his fuel pump could "adapt" and give a higher pressure on demand or some bs. get the walbro, you wont go wrong with that. stock internals can hold, but i would recomend upgrading before too long. that way you can make reliable power.
