Pros & Cons BlueChipDiesel VP44X vs a timing box

[flagmanruss]

"In this case we found a way to get better fuel mileage and a little more power on some trucks. This pump has ALL the upgrades and improvements that our exact replacement units have." "What we did to achieve this goal was to mix and match parts from other VP44 pumps to advance the timing mechanically and optimize fueling rates for better mileage." "If you are presently or plan on advancing the timing with an electronic plug in device or programmer don’t buy this pump as we are only doing mechanically what those products do electronically. " "The Special X pump is made from all Bosch made parts. It does not have any aftermarket or modified parts in it, so this allows us to sell it with the Bosch 1 year unlimited mileage warranty." This VP44X pump seems to give 2-3 mpg improvement. Is it preferable to do this mechanically? Or to advance the timing electronically (which can be turned on & off electronically & alternative tunes utilized)? http://www.bluechipdiesel.com/bfmVP44.html Thoughtfully, Russell

I think the bluechip route is a huge waste of money. A regular pump and an edge ez or quad xzt is the same thing.

Problem with the Special X that I've been told from other forum members that the Special X pump timing has been advanced during the build of the pump so adding another programmer or chip on top of that will over time the engine cause a degrade in economy and performance. Stick with a stock pump you'd been MUCH happier. As for buying a pump form anyone I would research the warranty more that anything. Because I heard tales about getting a great pump but being shafted when it was time to collect on the warranty. Tales of pulling pump apart and blaming the customer of poor fuel, water, etc. Won't do you any good to buy a pump and then have a issue then have to buy another because of shady warranty practices...
