Just came across an interesting product from Racechip out of Europe. Their GTS 5 product has a version for the Grenadier.   I appears as if it does not remap / overwrite your engine software but houses the software  in a separate unit.  With the optional phone app you can change drive modes from race to eco (not sure if you can do this while driving.... that might make me nervous) .  Adds roughly  50hp and 50 LB ft of torque and most interesting up to 20% increase in MPG.  Does anyone have experience with this or any other similar products.
