February 15, 201510 yr Owner My personal view is they are too expensive for what you could buy at CPP Diesel, Vulcan Performance (Industrial Injection) or even DAP (Midwest Injection). These three vendors all sell pump right at $1,100 where for the same then with BC its $1,800 with new PSG like the other three vendors.
February 15, 201510 yr Oh boy I don't want to write out my story again... If you really want to know go ahead and ask but for now I'll just say stay the heck away from them!!
February 15, 201510 yr Author Thanks, I was just reading about their 'special X' pump. little more hp, little more economy... all for an additional 300 bucks... That would put it well north of 2k..

I'm not exactly sure about the Special X pumps but I know the "HotRod" pump are modified internally for advanced timing so you can't use any programmer or module on them. So when they talk about modified pumps with more power and economy typically that means as a standalone. We you start stacking more timing it might become a bad thing. Hence why most will suggest stay with a stock pump that allows you your choice of module or programmer.

Hence why most will suggest stay with a stock pump that allows you your choice of module or programmer. What I took away from their description of the special X, was definitely more timing.. from Idle on up... and also expect the engine to rattle accordingly at idle... I bet it starts harder too.. they didn't elaborate on what they do, but apparently they swap some things around inside.. I don't have a tuner now, but like you said, we could duplicate electronically what they are doing mechanically, plus able to go back to stock if needed!
February 16, 201510 yr Owner Also counter productive ot the MPG fooler. Being the fooler uses temperature to allow the ECM to retard timing.
February 16, 201510 yr these guys are local for me, when my vp44 finally crapped out (electrical) i took it into them, after a 30 min chat with the tech, i just bought a "new" pump they had on the shelf. very knowledgeable and found out a couple things about these vp pump, http://www.dfispdx.com/

That is the main reason for electrical failures on our truck is a bad alternator diode feeding AC ripple to sensitive electronics.
February 16, 201510 yr In reading Blue Chip pages... it says that the Special X VP44 uses genuine Bosch parts from other applications to advance the timing mechanically. I believe the total advance is limited by the design of the VP44. It says the special X pumps do mechanically what a box or tuner does electronically. http://www.bluechipdiesel.com/better_fuel.html And advises not to combine a Special X pump with such a tuner. I find the electronic choices preferable... like my XZT+... because I can switch to stock at the flip of a switch. There are NO New VP44s in the USA. All in the US are rebuilt... to some degree. Blue Chip makes a big deal out of upgraded parts & housing... and computer. It's my understanding that there are only a couple of shops with the test bench needed to set up the VP44. Blue Chip doesn't have one.

February 16, 201510 yr naw, it was not this, its was the typical solder issue that is known for the vp44s during that time frame. (its is documented case of cold solder joins on the board that fail over time) it happened during a very hot set of days. the noise in the electrical would show up in the TC Lockup flip flopping long before it gets bad enough to take out electronics . My lockup is my early warning devise that my battery connections are needing cleaning to tell you the truth, i am surprised everything survived when my ecm decided to allow the regulator go on strike. speaking of ECM, who offers a good replacement?

February 17, 201510 yr There are more shops advertizing Bosch test benches now... maybe as many as 30 in the USA. Most of the ones listed are in the Western states?

Could you get me a list of them please Russ so I can update my list in the article database. http://articles.mopar1973man.com/2nd-generation-24v-dodge-cummins/25-fuel-system/247-bosch-certified-vp44-injection-pump-rebuilders
February 17, 201510 yr Let me work on it. Update: Generating a list. On page 6 of search results... still more search resuilts to go. Edited February 17, 201510 yr by flagmanruss
February 26, 201510 yr For safety sake test your alternator for AC noise output. That is the main reason for electrical failures on our truck is a bad alternator diode feeding AC ripple to sensitive electronics. How do you check the AC noise output? I'd be interested to see where mine is at as I'm still running a stock VP and just hit 170k! I want to keep this baby going as long as I can!
February 26, 201510 yr Owner Here is one video. https://www.youtube.com/watch?v=MGaHaIXZioA Here is my video. Just remember to probe the BATT terminal on the alternator. Just like the truck I just got done working on. It ate the VP44 and the ECM to some degree... http://forum.mopar1973man.com/index.php?/topic/9720-wait-to-start-light-stuck-on
What's the skinny on BC? yea, nay?
