The
first product we tested on our 2011 Chevrolet Duramax was the
TS MP-8. The MP-8 is designed to give the LML engine up to 100
extra horsepower. It achieves this by raising the fuel rail
pressure of the engine. On the 2011 it connects under the hood
to the fuel rail pressure sensor on the driver’s side
of the engine. The module comes with a infinitely adjustable
knob that is used to control the amount of horsepower that the
user needs, from 0 or stock to 100% which is 100 hp.
With everything on the Duramax’s usually being in close
quarters, it was nice to see that on the LML the fuel rail pressure
sensor was easily accessible, making installation of this module
a 5 minute process. Another update to the LML engine is that
the Fuel Pressure Relief Valve (FPRV) no longer needs to be
shimmed to accommodate the fuel pressure boxes like the MP-8.
Stock operating pressure of the LML fuel system is now as high
as 29,000 psi whereas the the previous versions of this engine
normally operated at the 26,000 psi range in the upper regiment
of their power demands. On previous engines this would normally
cause a need for a race plug or a fuel rail “shim”.
Going into the test we were excited to see that our customers
could have 100 horsepower in 5 minutes.
