he600wg turbo for cm870

[Rawze]

going from a VG turbo to a non-gt turbo will cost you a LOT of fuel milage. The optimum fuel-air mix for the ISX goes to s$it when you do this.

Also, the bigger the turbo, the lower the fuel milage will be overall due to having to spool up a much heavier turbine.

stop listening to the idiots over on socal medai... they will steer someone down the wrong road in a hurry.


you want to save more fuel.. learn to drive by your boost and pyro gauges and learn to not press the fuel pedal so hard up the hills. No amount of modifications can can beat how the person drives their truck when it comes to fuel savings.
