0-60 (MS confirmed in 4.9 seconds, speedo is off. virtually no launch, this is on my daisies and 185/60-14s)
62-136 (MS confirmed in 21.8 seconds, speedo is off. 60=62, 130=136)
Before anyone gets grumpy, the 0-60 run was done on a highway onramp, and the long pull was done on a rural road somewhere in California with plenty of visibility, no trees on either side (no place for deer to hide), and no other cars in sight.
14psi, my spark map, my fuel map (based off Jerry's MM9495 basemaps). I'm estimating power at 230-235whp. An interesting note is that I have pretty much maxed out my 460s, so in addition to Toyota COPs and water injection I will be jumping up to 550s and retuning. Dyno time in May, and I want 250whp on a GT2554R.

BOV is an eBay generic POS, IIRC it was marketed as a bypass valve for a VW 1.8T. These are with the REI camera mount.

I'll go over my datalog from Saturday when I hit ~230 and check out the injector duty cycle.
Some day when I grow up, my Miata will run like that. 
In the second video it looks like there's a little stumble when you get back on the gas after shifting gears, what's causing that?

Stock fuel pump, OEM single-feed fuel rail. I am pretty rich, 11.4ish to redline, so I could probably lean it down some and bring the DCs back.
I shifted pretty slowly in the 2nd run. The first delay is me rolling back into the throttle, since I am still getting boost overshoot (stock wastegate). It takes me 8/10ths of a second to get back to power after ther 4-5, and over a second to get back to full power after the 5-6. The blip at 108mph is the overboost protection briefly kicking in.

I wouldn't lean it down off of the dyno. My car makes better power when "rich". Perhaps yours does too. If anything, it's a tad safer in the 11's.
I'm voting for a gear change to 3.9's or 3.6's. I couldn't believe 3rd gear redlines at 60. Maybe it's perfect for you but with the wide power band 2554 gets I'd want 1st, 2nd and 3rd to be more useable.
Nice vid though. This isn't M.net, I'm not sure you have to worry about explaining your safety precautions. Good that you're not doing that in traffic unlike the now dead dick on the sport bike that passed me doing way over 100 in heavy freeway traffic recently.
