Based on the reported gains I would say the results are pretty much what I saw with my Renntech program on my car.These 1/4 mile times with Drag Radial are not real world for most on this forum since we are running stock sized street tires.
Thanks to AMG for letting us uncork so much power with a simple ECU tune!
I will not mention names just yet, as those members are currently getting their tune re-evaluated, but hopefully, we'll get more news within the next few weeks 
Also, all of the RennTech, Kleemann, and Powerchip dynos I've seen were between 420 to 430 whp in 4th gear and on a dynojet. I've never seen a RennTech or Kleeman 63 tune showing 450 whp on a Mustang Dyno and in 5th gear.
We need more "tuners" cars at the track to compete with each other, and let the best tune win...... and so will we as a community

Drag Radials = 11.596 @ 118 mph
Street Tires = 11.73 @ 122 mph

C63 09' LSD traded for 2010 GT-R
I would imagine that each cars HP results will vary bone stock.
So wouldn't the best way to have a shoot out be:
same car
same driver
one day
various tunes each with multiple runs
on the same DYNO or DragStrip?
This would remove car to car variables and soley rely on the one modification.
I would imagine that Drag Radials would yield more consistant results in the 1/4 than street tires. I find it interesting that the speed trap is actually higher on the street tires is the overall diameter the same? or does the car have to make another gearshift (smaller diameter) to get to the traps knocking off the 4mph?

At the track, all RennTech, Kleemann, and Powerchip tunes are welcomed to use drag radials as well, but so far, only 2 have done it and unfortunately the results were no where near Andy's 11.60 I will not mention names just yet, as those members are currently getting their tune re-evaluated, but hopefully, we'll get more news within the next few weeks
