Don't know in a my life depends on it way but the specs are the same for both DCT & 6MT engines. The sport N55 kit aka PPK cannot match the torque of the IS N54 package although its advertised at the same 320BHP. On a dyno the N55 PPK does about 295whp & the N54IS 320whp. My 135is has the N55 with the PPK on a 6MT but the DCT's use the same N55 PPK engine in the 135is version.
