Invention, Design, Prototyping, Research, Development, Testing and Manufacturing;

 We stock Stanadyne PMD/FSD modules, resistors and other Diesel Fuel Injection parts, Stanadyne is the OEM (original equipment manufacturer) for the GM 6.5 Diesel injection system and despite another latecomer NON-oem making a PMD/FSD Module, we still find Stanadyne's units the most reliable when mounted on a proper PMD/FSD cooling product as our PDC, Pump Driver Cooler.

 Our founder Jim has been in the Automotive Industry since 1978 and has worked with and for Major OEMs and has been working on the GM Diesels since their introduction and our shop still has one of the early GM 1994 6.5 Turbo Diesel trucks that Jim bought in 1994! (see pic below).

  Above picture is of an original 1994 Chevrolet 6.5 Turbo Diesel K3500 Crew Cab Dually outside of the warehouse on a lift for a regular servicing and checks.

 Jim solved the problems plaguing the electronic fuel injected GM 6.5 diesels and turbo diesel engines early, one of the pioneers and who perfected the reliability and power upgrade innovations over a decade ago that are still in use, being produced and sold here to this day. Jim added the 6.5 Diesel products line after addressing the problems with his own truck and those of prior GM diesels, and was asked if he'd make/sell products to those who heard about his work and solutions.

 For over 16-years Jim previously owned and a large 40,000 square foot Automotive Center within a mile of the coast/beaches which included the following; Automobile Dealership, High-Performance Automotive Pro-Shop, Auto Repair Shop, Automatic Carwash, Self-Service Car Wash, Hand Wash & Detail Center, and utility/car trailer sales.

Above is an older picture of testing one of our prototype Water/Alcohol-Mist-injection systems back in the day.

 Our inventors/designers have some of the best equipment and tools at their disposal like; CAD, CMM, CNC, 5-axis machining, laser prototyping tools, many various other tooling and design abilities, and much much more. These tools aid in the creation of prototypes of first rate product designs.

 Above picture is of part of the body of high speed car on granite slab table of  the CMM for accurate measuring.
 The vehicle's owner later went on to set the Land Speed Record vehicle for fasted Duramax diesel powered vehicle!

 We felt it necessary to post the pictures, information and this page on our website about our manufacturing and production due to some unethical and unscrupulous sellers and their promotional site 'forums' that were badmouthing us to try to make sales of items they sell instead (shame on them!). To read about their methods click here.
They have often badmouthed and slandered by saying
that we're; not real, are fly by night, new operation, operate in a basement or garage of some apartment, only making/selling a few items that don't work, do not have a phone #
(it's on this site's contract page, and the old site), etc. all while pushing their stuff via web forums and a sales oriented diesel page "online magazine" site, or diesel place misinformation site, but on this page as you see, their badmouthing and untruths are proven to have no validity!. The strange thing is that if one looks up their addresses on; mapquest, google or yahoo maps, most of their locations are homes in rural farm areas, and one that is a commercial address is that of a building that is found to be for sale or lease! There is nothing wrong about home-based businesses, if they are not mudslinging at those who have been around long before them and operating in a professional manner.

 Our leading products have proven themselves over the years, but prior to that they were rigorously tested to assure that only the best quality, design and products are offered to our customers. But the testing did not stop there, and continued to make sure no problems our after long term use in production and many products have been used on commercial vehicles during that time, and we still operate most of the original test units. We have never had a PMD/FSD fail on our PDCs!
