A PD SC pretty much makes the same boost everywhere so it's just like driving a larger engine. Below is a 1/4 mile datalog from the Camaro with a TVS 2300 on a completely stock LT1 running a 10.2 @ 138MPH. You can see that it makes full boost (even during shifts) from launch to the end of the 1/4 mile (magenta line). You can also see the short shift from first to second (a bit of wheel spin) that cost me about .3, on the next pass that I fixed this and ran a 9.93@140.
It drives like a stocker around town and then pulls hard everywhere at WOT!
In the past, the PD systems that were available didn't have the inlet design and intercooler capacity to maintain power at high engine speeds.
While that problem still exists in some of the OEM systems, the latest aftermarket systems don't drop in power anywhere, they just scream from idle to redline.
