I ordered my spark plug gauge from Amazon and got it in yesterday:
Measures .020, .025, .028, .030, .032, .034, .035, .040 so it's just what I need.
Mike at 5 star said that .028 should work well for the 87 through 93 Octane tunes that I got from him. If I'm going through the trouble of pulling my plugs to gap, should I just put new ones in (I'm at 10,500 miles now)? SP534 plugs look to only be $4 each from Oreilly.

U want to exercise extreme delicate caution on the Iridium as it so easily damaged.

Changed my plugs today, took me about an hour. Gapped them to 0.030". Plugs were NGK LTR6IX-11 and they were ordered from amazon as nobody in town had them. They came out of box gapped at 0.40-0.42.
Pulled original plugs they were gapped at 0.038 x 1, 0.039x2, 0.40 x 2 and 0.41 x 1. Truck has just over 20,000 miles and is 2012.
I didn't have any rough idle or problem, but my gas mileage has sucked since I got this truck and I'm trying anything that might help. Obviously no feedback on that point yet.
Had one plug that was quite a bit harder to get out, and I did apply a bit of anti-seize to each new plug. I set my wrench to 120 inch/lb (a bit under recommended since I used thew grease, totally made this up on the fly, but looking at the rotation of the plug after contact with the head, it looked the same amount as I would do if I wasn't using a torque wrench, so I felt ok with it).
Highly recommended video if you haven't done this before, made it very easy for me:
