When you increase boost above 14 psi research has found that the factory fuel injector become inadequate.

The injectors must be able to supply a large amount of fuel at wide-open throttle to prevent high rpm lean out,
i will upgrade the pumps once i see my numbers from the dyno for the apten. Our stock ones are good till around 16psi,

Ummm yup...do the math....405 rwhp w/out the phenolic spacer and efan (i haven't had it dynoed with the spacer and the efan).....they add 13-18 each, then 30 hp for the exhaust (full exhaust not just a muffler) and another 25-35 for the ported s/c.....with the right tune (JDM) it will easily hit 500....

if i had a built bottom end i wouldn't have bothered
it was a precautionary move for me, we all know what happens with these motors when you run lean,
i have noticed a big differance in the higher rpms since replacing them

actually (not to start a pissing match lol) when mods are combined with other mods, they typically increase the combined numbers.....example...with just a chip your HP may increase by 20. But add a cool air kit (which may add 15 alone) and your total HP may increase by 40.....you see everything works off of each individual component....change one and they all will change.
