Pinion angle is the included angle in the rear u-joint, AKA the difference in angle between the drive shaft and the pinion centerline. Nothing more, nothing less. The only reason to adjust pinion angle itself is to get it to be about 2 degrees down under power.

Are you sure you're not topping out the front suspension? If the front tops out too quickly, it will unload the rear tires, especially on a lower HP car that cannot lift the front tires and carry them. On a really good track it'll still hook because you don't need as much weight transfer to maintain traction.
