yes, it has. I just got back...went about 50miles. When I first got behind the wheel, I was NOT impressed. It felt totally stock...very little lope, it wasn't peaky at all...I couldn't figure it out. Then I put the hammer down. This thing will spin the tires in 1st gear hi/hi, where it never would before. It has loosened up a bit, and I am liking it more and more. It feels like a totally stock truck...with a shitload of torque. Where my last cam was a little flatter until my vac advance kicked in(and then hold on) this thing is strong all the way from idle.
It idles WAY smoother than it ever has before...and actually so low(read:where it is supposed to) that I need to step up to a 20w50 oil; there is a oil pressure related tick until it gets back to 35psi. It is running a little warm I think, at around 220, but I have not tuned the carb for this cam, and I am waiting on a BVSV from Toyota tomorrow to replace one that I broke.\
I should note that I have the adjustable cam gear set at stock right now, and am running at stock distributor timing instead of my usual 15*.
