PSC Pump Advantage ??

I'm running the stock pump with a new PSC Steering Assist kit. It works fine although in fast turns, it feels like the pump falls behind on volume and pressure. It's ok for now and has considerably more power in the rocks. Two questions. Are there any warning signs of impending stock pump failure? And , how does the PSC pump affect the performance compared to stock?

If you have 6 speed manual stick with your stock pump and get it ported they work much better than psc pump if yoh have an auto psc pump is good more high flow but you need to run the their bigger reservoir with filter and a ps cooler

Are there any warning signs of impending pump failure or does it just lockup?

I'd guess it will get really noisy before it goes.

I just installed the new PSC pump with the chevy internals and the no leak reservoir on my JK. The installation was very straight forward and simple. The new pump made the ease of turning the same at all rpms. There was no more lag in the steering at slow speed. The steering feel was greatly improved in every aspect. Worth every penny in my book.

I wish I knew the answer to that also. I've heard of some fairly major issues with the full PSC system and the 6-speed trans

because rather than being at 800 rpm as you turn into a parking spot, generally you're at a higher RPM (since your foot is on the clutch and a quick rev is all you need) which turns the pump faster.

31 jeeps in... still have issues

PSC setup does NOT work well with manual 6 speed transmisson that is bec of low engine idle speed.

With Auto transmission the engine idle speed is up all the time when in drive compared to manual so it works very well.
