Could you explain how the sequential shifter works?
basically you push the shifter either forward or backward to shift down or up, so you can't miss a shift because you go through all the gears. Not sure if this is the oackley shifter? but I have seen it in action and like it:

Sequential System explained...
The system was designed by a Siemens engineer for Porsche 996 Cup cars. In the end Porsche decide not to use the system (due to cost at the time) and the designer bought back the rights to the system which has now been defined and is marketed by Oakley Design.
The only physical change to the car is to remove the shift unit in the car and replace with the taller sequential shifter. Remove the two OE cables and replace with one cable supplied. The unit then bolts to the side of the Porsche gearbox. No welding, bending or permanent modification is required. The system is electromagnetic. It receives a signal from the shifter in the car. The driver pulls back for first, again for 2nd, again for the 3rd, 4th, 5th and 6th. Reverse is one push forward of neutral.
When shifting from 2nd to 3rd the shifter does the sideways movement on the box in addition to the fore or aft movement and the same from 4th to 5th (effectively across the gate).
Use of the clutch is required as the system still uses the OE gears.
The result is shifting is about twice as fast as OE. It removes room for error especially when track driving i.e 5th to 2nd which is often catastrophic to engines and transmission.
In addition shifts are much easier mid-corner especially when pulling larger G forces. With this system it is just a quick ‘snatch’ of the gear and keep accelerating.
It makes much more sense when driving it….!!!
This system is ‘fit and forget’ ie. it needs no maintenance. Also the car can be reversed back to OE H pattern if and when required.

To put the vehicle in reverse with this system is a simple as slightly depressing the clutch and shifting forward into reverse from neutral, the digital gauge pod will show an "R"

i currently have about 3500 miles on her and she is awesome. i am considering a full set of rennline pedals with adjustable gas pedal as heel/toeing is near impossible with the pccb's as the brake pedal at full brake is way too high relative to the gas pedal. also considering solid engine mounts, but who knows.

When you are going fast enough and really hard on the brakes, all is good!
I had the same thoughts when my PCCB were new, with their great initial bite, after a couple of track laps all is normal.
