Yes and it can vary quite a bit, mine has went as higher as 70-80psi and higher revs on both the stock and my aftermarket mech gauge.

I wouldn't give much weight to the actual numbers the stock gauge is giving you, as all the ones I've personally seen have been horribly inaccurate.

Mine idles at 55. Thats with 10w40. I dropped down from 20/50 cause the pressure seemed plenty high to me. 120 @ idle ...... I'd hate to see it @ 9 grand or when its cold.

That's why I don't rev it cold.
And yeah, that's with 5W-20. Putting a stock regulator back in soon.
