Like escargot, the Kleemann turbo upgrade for the powerful M157 engine is not for the faint of heart.  Reserved for those who desire mind bending performance from their V8 Bi-Turbo engine, our new turbo upgrade offers a complete update of both the Compressor wheel and Turbine wheel allowing for faster spool-up, increased boost pressure and drastically improved efficiency for the already powerful AMG 5.5 V8 Bi-Turbo engine.  Coupled with our highly developed engine management software, this upgrade will leave you pinned to your seat back with your eyes bulging in astonishment.
