Default Things to do before hitting the dyno.

So, im going on friday to do some power pulls on the dyno. My tune is kind of ghetto. Its basically a spark map that i stole from here (i know, i know but i hear/see no knock) and a fuel map done on the street. The car feels great! Anyway, my question is, what should i know/do before i go to the dyno? I'm not going to be doing any tuning there, just getting a number. Also, they are charging $50 for 3 pulls without them sniffing my tail pipe. Decent price? I have a wideband, do i need to pay the extra $25 to have them give me a second afr?

Datalog all the pulls. See if they'll give you 5-10 minutes between pulls to use VE Analyzer on your fuel maps. Put new plugs in it the day you plan to go to the dyno. (don't care if they're a week old, change em).

Check for/fix any and all leaks.

I can't tell you how many times I've read; "got XXXwhp on the dyno, but was leaking from one of the hoses so I couldn't make full boost".

All good ideas so far. I can say from experience, if your bringing a laptop, bring the cord or charge the battery. My **** died on me at the dyno, luckily right after the ******* last pull.
