Here is the initial info off the raw data chart.
Absolute barometric pressure: 30.26 in.Hg.
Vapor pressure: 0.16 in.Hg.
Intake air temperature: 63.7F
Gear ratio: 63.01RPM/MPH
Correction Factor: 0.95SAE
Here are the dyno charts as promised.

I am sad that the kit is not making full power as the A/F ratio went extremely rich across the powerband. You can tell by where it made the highest HP was when the A/F ratio became leaner at around 6k-6.1k RPM. (10.4:1) I should be bringing this back up to somewhere around 12:1 - 12:5.
I spoke to Mr. Stafford about this, and he told me that he changed a few parts on my fuel setup (within his fuel system) as in comparison to the Vibe, and the Matrix. He ended up setting up my car with a unit that'll suppy enough fuel to a 500+ HP FI application. Mr. Stafford will use this info to setup future kits. So through me, everyone will get a better kit. The GT that's being worked on right now will also receive a retooled fuel system. That fuel system will be dyno tuned for optimal A/F ratio to give better output. As to why my car wasn't dyno tuned while it was at Stafford Fab., it was my fault for being pushy. I couldn't give Mr. Stafford more time to work on my car. Mr. Stafford is so commited that he will be coming back up to NorCal for a day to refit my car with the new fuel unit. :thumbup: I will post more dynos when that's done.
Also, he has recently found out that the Vibe dyno chart was off. The Mustang dyno that was used was heavily mis-calibrated. So the 225 HP/225 TQ was off.
For those who had doubts about the fuel system:
I asked for the injector pulse to be measured during the dyno. My injectors were running 80-85% duty cycle. They were NEVER maxed out, even with the fuel system supplying too much fuel
Here is another chart to show my base dyno w/o the turbo vs. turbo.

Through my discussion with Mr. Stafford, we will be expecting more out of the car once the fuel system is added. In the mean time, I will be running safe at the cost of burning more gas than I need to.
I will post the pic of the old air filter element to later on today to show the power of this turbo.
I do apologize for not dynoing at 10 PSI or anything other than 7PSI. I just totally forgot about it.
