Spark plug question...

[STUNNAH]

Changed my plugs...They were black...Can't remember what black indicates...Is it to much fuel or to little...Plugs should be brown, right...

black= rich mix
white=lean mix
tan color=just right

Thanks Rubber...Couldn't remember...Guess I'll put the PC3R back on and try to lean her out...We don't have a tuner where I live...

no prob stunnah....go in small incraments with yer PC , one line means alot if ya know what I mean . Better rich than poor....kiddin' , better rich than lean , rich means foul'd plugs,dirty exhaust,etc....lean means she gets hotter,burns valves,etc.....you know the drill . Gettin' on a dyno is , contrary to popular belief , not the exact best way to tune.
An EGA , exhaust gas annalizer ,coupled with a dyno is actually the way to go...but who's got access to that.
My GUESS....she's rich in the bottom,lean in the middle,most likely ok up top . I'm guessin you've got an' aftermarket exhaust,probably a K&N filter. Those Power Commanders always seem rich in the basement . Lean up yer low , wipe the black crud outa yer tail pipe , go 4 a blast an see how she is when ya get home . Remember....small increments....just like suspension tuning....its tedious....but it pays off in the end .
Have a good night.....RSD.
