Mercedes M278 4.6L Bi-turbo Engine Tuning

 Mercedes E550, CLS550 and S550 customers will love this VAST tune to take the full advantage of their 4.6L bi-turbo V8 power plant. 

 Real world gains you can feel on the street of to bring you to roughly 475hp and 585ft-lbs of torque are available for a healthy vehicle on 93 octane fuel. We recommend new NGK-91006 spark plugs installed with a .026" gap.

 Another tedious, expensive, but somewhat important item to note for higher mileage vehicles is to bring your vehicle in for a carbon intake tract cleaning. 

 Feel free to inquire about our custom VAST remapping for turbo-back exhaust, intake modifications, cylinder head rework, E85 blends or race gas. As always, all of our Bosch Motronic tuning is done in-house, giving you direct support to optimize your vehicle's needs.
