I've heard of 'Stage 1' owners leaving the injectors in and using the stock PCM for "Many of Reasons", my question, can you (we/us) just leave the bigger injectors in permanently???? Thinking of putting the stock PCM in and increasing the boost manually, and the fuel 'issue' and boost 'issue', will compensate for each other. Maybe even have a new PCM installed for the 'engine-miss @ 5300rpm'.
I know some owners have done this temporary, but for the whole warranty (70K) to last, and to have a blast, could/would this be OK?????Thanxxxx Stew |

Your car will run rich with the stock PCM and bigger injectors. Rich does not mean more power. A car's computer is programmed with the flow rate of the injector. It tells the injector how long to stay open based on input from sensors or a lookup table based on the known flow rate of the injector. The "on time" is the pulse width. A bigger injector will deliver more fuel for a given pulse width. I am not sure whether the fuzzy logic will eventually compensate for this but the base programming flaw will still remain. I have more experience with Mustangs, but bigger injectors there without compensating did not create more power and usually had very poor idle characteristics.

As far as I know the 2004 version uses those bugger injectors, therefore the increase to 220 HP.
