I think Brainy and I and maybe newbsauce are gonna try to set up a real deal TUNING dyno day in northern va. I'm shocked how well the hydra autotuned on the dyno. First run was ugly AFR ranging from 11 to 13. second was within a few tenths of my AF targets. It's solid. There's a couple loading dynos out here that would make short work of a fuel map and timing map shortly thereafter.

Well, fairly succeeded. My dyno operator wasn't quite familiar with the Emanage/Autotune setup, but he picked it up quickly.
I got 185whp and 191 ft/lbs at around 10 psi. Unfortunately, my boost trails off big time after about 4500 rpm, and i end up with an early spike to 12 and then a drop to about 9 for the rest of the run. I drove two hours to this shop because i trust their reputation. My drive up used a half tank of gas. My drive back used only a quarter tank.
I was running 11:1 AFR's pretty much everywhere before. My baseline run only netted me 134whp. lol. Everything seems better now. I just need some bigger injectors, and a helper spring for my greddy wastegate, and I'll be golden.
BTW, since I think I'm the only one here who ran a Dyno Dynamics run this weekend, DD dynos typically show values 13-15% lower than DynoJet dynos, so with that in mind, my adjusted totals are 213 whp and 219 tq.
That's close enough for me, and i have room for improvement.

Didn't learn: why for the 2nd year in a row my car makes 2psi less on the dyon than on the street. WTF?
Learned: 2 sizes up in turbo is probably too much. one size larger may be jjjuuusssttt right.
