Audi S4 Stage 3 Dynojet Dyno Pulls at BCP - 429 WHP / 437 lb-ft. Bonus B7 RS4 Pull at end...

I finally took my S4 to the dyno! I took my car to BCP’s (Boost Controlled Performance) Dynojet dynamometer for a few pulls. The pulls were made on a custom Mike Shimon pump gas tune boosting to 22 psi peak. Final numbers: 429 WHP / 437 lb-ft For comparison, the B7 RS4 at the end of the video put down 328 WHP.
