For those not on Facebook...
Was at DB Performance yesterday having Danny work his magic on the cobra. Recently all the gas stations in our area quit carrying anything higher than 91 octane. Currently the nearest station with 92 is nearly 20 miles away. So... in combination with the fuel mods (Removed BAP, then added Fore Hat, Ford GT Supercar Pumps, Dual FPDM, enhanced wiring for better voltage stabilization)... I had Danny tune the car to run on 91 octane fuel as its primary (and now ONLY) tune.
With VERY good air (51*) the car put down 540rwhp ... UP from 517 on the old 93 tune (with BAP).
The results were astonishing to say the least. I went in expecting to lose about 20hp on the tune to lower grade fuel. We also saw the boost peaking at 16#. Have all the charts at home I'll scan in eventually and get them posted up. The chart below is a camera-phone shot of HP and Air/Fuel.
It's kinda dark, but the air fuel hovers around 11.6 to 11.8.
We did get to 544rwhp at one point, but the car exhibited a knock at the torque peak (just one slightly audible) so we backed down the timing a bit in that area of the rpm range and all is happy now.

Thanks DANNY!
