For Tiptronic transmission equipped vehicles, we highly recommend a GIAC chip for your transmission computer.

The GIAC trans chip addresses the "lazy" shifting as delivered from the factory, without losing any smoothness. Users of this chip have described the results as similar to "superbike" shifting! The GIAC trans chip solves gear "hunting" under full throttle caused by the massive torque of a well designed engine chip.

The GIAC trans chip is a "must have" for all tiptronic transmissions, regardless of the chip in your engine computer (even stock.)

Also please note that all GIAC chips advertised on this site are for US spec vehicles unless stated otherwise.
