The 00 R came with the standard TCV and a claimed 261 bhp. When I bought the car it had the Rica tune and a supposed 312 bhp and around 300 ft/lb of torque. Are those real? Who knows but the car is fairly rapid. The car is running the IPD boost TCV and from what Volvo told me it is running in around 18 psi boost.

The "Porsche" Pierburg unit is more stable at higher boost pressures.(7.22908.03.0)
