Cobb's staged maps for the cars with intake and exhaust cam timing control come with a dyno developed map that most tuners are then leaving alone for stock turbo cars.
They did not repeat the work for the inlet cam timing control only cars. My road based acceleration testing revealed an increase in torque from the change, but no dramatic change in boost threshold, although this has dropped considerably with the new boost control method, on a stock car you can now have 1 bar at about 2500 RPM and still have it at 7000 RPM, with 1.2 bar from about 3000 to 5600 RPM. Not quite as high/wide on the boost as you can get on a 4G63 on a stock turbo (although I am talking basic breathing mods here so not entirely comparable), but it drives beautifully as a flexible road car.
