Not exactly
Power is the rate of conversion of energy, in the case of an engine it is how fast can you turn petrol into exhaust gas and bung it down the pipe.
The "injector thing" is the maximum amount of fuel that the injectors can deliver at high revs when air is being pushed into the engine. That limits the power that the engine can produce. This assumes that you have opened up the exhaust flow by changing the manifold and exhaust to let it out the other side.
"Running lean", connected to lag, is not getting enough fuel at lower revs when you floor it.
Thats what i meant, the car running lean when floored at low revs or the 'lag' as ppl say. As i said before temporary fix is to ever so slightly depress accelerator, rather than flooring it immediately. It works, crude as it is.
Kazi: No it wont. Still not enough fuel from my understanding.
I always thought the "hesitation" when suddenly flooring it under 3000rpm was due to pressure waves between supercharger and throttle body.
Slowly flooring it is indeed the workaround, and mine actually pulls from 1500rpm to the redline without any hiccups (nice metallic sound from the s/c at 2000rpm).
This would indicate there's no problem with the fuel mixture, but that it is merely the crude way the s/c switches from idling through the bypass to making pressure.
Unless your mods to inlet and exhaust are so extreme that it would need more fuel than my setup (mine has a decatted manifold, but standard TTE airbox). But then again at low rpm there shouldn't be a fueling problem, only at high rpm where it actually needs a lot of fuel.
