Hi, on my c32 2001 l have a 185mm kleeman crank pulley, I also have a 65mm s/c pulley, car runs good with no fault codes, my question is should I keep the 65mm or put stock back on as im worried about over boost,also if the stock 73mm pulley is put back on will power increase or decrease as I don't know if overboost makes the engine less powerful.

I'd be really careful about flooring it cause even with JUST a 185, without a tune you can run lean.
Stacked without fueling mods, I'm sure you're def running lean.

thanks gramma_benz for reply, I have aem320 and 550cc fuel injectors, dyno showed perfect afr's. my worry is maybe the engine can produce more power and im not letting it buy keeping the 65mm as I don't know if overboost is restricting the power. its got a jerry tune and like I said it runs really good.

Don't worry about the overboost. The ECU will through a code if you exceed the max. Worry about the extra heat that high boost will generate. That will rob you of power.
