You car is completely stock except for Maggy?
Did they dyno your car after the install?
Did they do a baseline before the install?

The car is completely stock except for the Magnuson kit, and the Nitto 555R2 tires that the Magnuson installation made necessary (with the OEM tires, the ECU engaged traction control any time WOT was applied, and kept the TC on even at th ehighest speeds I have ever taken the car to - about 85 - 90 mph).
Yes, Davenport dynoed the car after the installation, and the rear wheel hp corresponded to 650 crank hp. The 588 hp you apparently saw at the Magnuson website was likely the rwhp for a car equipped with the MANUAL transmission versus the 10-speed automatic. That represents about a 10% manual tranny driveline loss, which is about right for a manual. The 10-speed is slightly less efficient (I think around 560 rwhp so a 14% driveline loss). The automatic transmissions that preceded the 10-speed were far less efficient. The 10-speed is notably quicker in the 1/4 mile than the manual though, because it has more gears, and can shift quicker than the manual.
I cannot remember if they did a baseline run, but most shops do just to make sure they are working on a healthy car.
The tune I got is apparently a "standard" Magnuson tune for the Gen 6 Camaro, and is so conservative that I have zero worries about reliability or durability. That is what I wanted.
