i was reading an article and it said the neutral position sensor has an effect on injector pulsewidth. now, since mine isnt hooked up im wondering how it affects the computers decision.

I never connected my lower harness and made 277whp @11lbs back when stock. Food for thought.

Mine is not hooked up either, but I'm running a PFC, so I doubt it does anything.

I ran without mine hooked up for a while and then connected it. Didn't notice any difference either way. I have read what Carl stated before.
