For me.. I have not seen any difference in fuel consumption without and with MPPK. I also have RCU piggybacked as well.

Kzang, is the MPPK + RCU still doing it for you? Any reason why I shouldn't do the same? The racechip has been great for me but I am teetering on the fence about doubling up with the MPPK. |
Most definitely! Get the Mppk.. you won't be disappointed at the additional power and torque. You will be driving a SUV 0-60 in the low 5 seconds. The thing about the mppk is that the throttle response is also affected whereas on the rcu alone it does not. At least to me.
