Thanks for the great responses, everyone! I'll give the Brilliant and the Americana a shot. Looking forward to great results.
By the way, Steve, nice Shelby! I have an '08 that I took up to 604 bhp with a Steeda CAI and custom tune. Love the car, but don't drive it much, 8K total, so far. Did you drop yours at all? I don't notice in the mods. I'm thinking about it.
