I'm still curious about the fueling issues, my previous post must have been missed. But...

A quick question, which I may of missed before. With the increase in displacement how are the fueling issues being met.

In a Mass control situation the point is moot. But considering that our cars use a speed density system, the PCM has no idea on the 'new' required pulse width. If you increase displacement, naturally more fuel will be needed.

Is a rising rate FPR being incorporated, because the stock 1:1 unit won't cut it. Secondly, it still doesn’t meet fuel trim issues. From what I know there are no PCM mods available unless you have come up with them. But PCM mods would certainly solve this issue...

A simple way would be to add proportionally larger injectors. I would guess that stock injectors are about 30 lb/hr units. So by going up to about 33 lb/hr units would keep the fuel trim values near 0 with no changes made to the PCM.
