hi,
I'm thinking of taking my BA 5.4 V8 3v Falcon for a tune as I've put an aftermarket exhaust on it, but I'm confused as to what get tuned (I haven't had an engine tune on a modern engine with a PCM before). If they increase the fueling, doesn't the closed loop system detect a rich mixture and lean it out anyway? And if it's already too lean, wouldn't the system enrichen it? What other things do they do to increase performance? Thanks |
