So I had a customer at the shop
Well he wanted a Perrin pulley installed and had a question?
He said qoute: Suby Dude said that if I installed a lightened pulley on my REX that my car will misfire"...
You folks know what I said

Way to go Joseph... almost lost a sale hahahahahahaha !
I installed it on his car anyways. He will let me know if it misfires..lol

i won a GFB pulley set from mpj perf, but im not goin to say how, =some might take offense (its nothing bad, and no not mansecks)
im debating whether or not to just sell it and buy other stuff because how much does a pulley set do?

Joseph was somewhat correct.
I have documented many times, that insalling lightweight rotating components (flywheel, pulley) sometimes creates additional noise that OEM knock sensors mistakes for knock and triggers misfire code.
9/10 it was caused by a lightened flywheel. Once by a pulley.

Not saying anyone is right or wrong but for what it's worth we have sold over 200+ Perrin pullies and have installed over 50+ without one customer coming back to us with a problem.
With respect to the stock pulley's harmonic balance (sorry more than a few beers into it) and how it's replacement cause skewy knock thus misfiring I would imagine this may depend a lot on manufacturer specific designs.
I always thought the majority of those funny misfire codes came from rich conditions or funny little piggy management system freaking out at weird loads (ala Unichip) although I can see how a extremely light flywheel may cause some misreading with the ECU.

Do not misfire after what? Not sure which post your referring to there mate?
Agreed have seen misc rattles and such throw codes but never pin pointed them to a aftermarket pulley though.

I know which DVD that's off of, it's off of Battle Stage. My favorite borked translation, "Snow Cold" or something. It was some really really bad translation. I only watch that when I need to laugh, ahahaha.
