When you have a lightweight, low gear, high Horsepower 965 you'll feel more when letting off the throttle.
Couple upgrades. Turbo smart hybrid diverter valve. This allows a % of the pressurized air to be released when closing the throttle. Better design. Also upgrading to the Tial 1 bar wastegate. Hopefully a quick accurate release of exhaust while saving weight. These two features are not welcomed in the collector market. But excellent upgrades for those of us not selling. Then replacing a new faulty fuel pump.

Next is another new interior. Can Can red by Classic 9.

Are you just going with a straight 1 bar spring in the Tial? My plan is to do a 0.7 bar spring with a manual boost control **** so I can dial it up to somewhere in the range of 1 to 1.1 bar as we dyno tune the car.
