Stage2+ Power Package by M-Engineering combines the leader in aftermarket injector technology, a motorsport grade quality wiring harness, and wraps it all up together with the M-Tuner Suite and Motorsport Tuning Package.  With this kit you will now be able to run E85 on your stock turbo equipped M838T and fully maximize the potential of the stock turbochargers on gasoline or ethanol based fuels.  

With Stage2+ you can now use E85 from the pump and have the same performance benefits as running MS109, GT260 Plus, and other race fuels, but at a substantially cheaper cost per gallon.

With live map switching you can switch between pump gas and E85 at the pump with the flick of the cruise control stalk.  

The perks of the aftermarket wiring harness are that you no longer need to cut up and repin your factory engine harness to adapt to the new injectors.  Your OEM harness can be removed and kept intact.  This harness is built exclusively for M-Engineering by Race Spec and is 100% Plug and Play with the OEM main engine harness.
