The dyno, along with customer testimonials, pricing, etc. is all on the website.

However, I've attached the scanned in dyno page to this message. Unfortunately it doesn't have the A/F ratio. Rick Squires, who tuned the vehicle, said it was in the low 11's.
The dyno run was done on an all wheel drive Mustang Dyno at Modern Garage in Murray, UT. You can call Christian at Modern Garage if you would like to verify. 801-262-4605.
Thanks for the question!
