DiabloSport P1040 Extreme PowerPuck Inline Power Module

Love it, so far. I've heard a few horror stories about this chip, but realized how many of these have been installed since hitting the market.Installed in a 2011 RAM 2500 6.7L HO 4X4 crew cab, long bed. Running the dial at approx 50%. I have noticed an increase of at least 1 MPG at 75-80 MPH (cruise control, level to light grade), 2-3 MPG at 65-70 MPH and a definite increase in throttle response, turbo spooling and top end power. I will add this, I am running this chip with a fuel rail plug, as opposed to the shims provided by Diablo. Not that there's anything wrong with them, it's just that I have it on good authority that once shimmed, the fuel rail valve lifts at a pressure value equal to or greater than that of what the pump can produce, so I am not too concerned about pressure spikes.This may be an old product, but it's brought new life and a new attitude to my truck.With just a few other mods, this chip can get me damn near 500 RWHP, of course I plan on building out the drive train transmission first before adding too much HP.
