I run a NOS Launcher on my '13 GT. I've run dry up to 125hp jetting and wet up to 200hp jetting. I can't comment on track numbers, but the Launcher makes the power VERY manageable, especially with a manual transmission and "less-than-perfect" traction conditions. I've used the Edelbrock controllers before also (on my old Outlaw 8.5 car). They are a little simpler than the Launcher, but they work very well.
