Not sure if Devin at PSR or Brenspeed get's the credit, but...WOW.

Ordered the new cam - Brenspeed's Detroit Rockers, and had Devin tune my '07 shelby.
Like a new car...old school sound...picked up around 30hp, but feels like double that in the higher gears. I hate it when these guys do such good work...now all I think about is the next mod. What a sickness.
