Thumbnail Filmstrip of 7.3 Powerstroke High Current | Voltage IDM DTC HFHCIDM Images
In addition to our normal rebuild process, the DTC High-Voltage High-Current units get two additional tweaks. The first step increases the output voltage to the injectors from 110 volts to 140 volts. The second step increases the current output by about 20%. This activates the injector quicker, holds it on (poppet valve open) more firmly, and keeps it on just a bit longer. The result is snappier acceleration and a more responsive truck.
After the rebuilding and modifying is done, we run each IDM through a 20 point test on the test bench, and then we run it continuously for 30 minutes at 3000 RPM and 3.0 milliseconds of injector pulse width which is longer and harder than you could ever run a truck in real life. When it passes this test, then it is ready to sell.
DTC been doing the high-voltage mod since 2004, and invented the high-current mod in 2008, and haven't seen any negative side effects to either the injectors or the IDM in this time.
Note: If you are seeing a P1298 soft trouble code after installing IDM, this is completely normal for an upgraded IDM and will not cause any issues.
Note: We do not test your core upon receiving.
*No returns on this product. Electronics can no be returned for a refund.

I read you didn’t need high voltage if you run a chip in Powerstroke forum? I have a TS chip . I want to do full force 180/30 injectors with new solenoids and the full force chip reburn. Is high voltage ok with future upgrades

High Voltage IDM's are a good upgrade for all injectors.

It's not required or needed. Will help throttle response slightly however.

Great place to buy from. Truck has never ran this great idle smoother and throttle response is noticeably better.

If you need a IDM this is worth the small extra cost over a stock reman IDM. My 7.3 only has a straight thru 3.5” muffler and an air intake, not even a tuner yet… I instantly noticed a difference on start up! Throttle response is much more snappy and it’s easier to keep up with traffic now! Plus the purchase from a company that pioneered the HV IDM and actually tests them is a bonus! Don’t waste money on a stock reman.. the 7.3 should have came like this stock.

Best customer service i received a damaged idm and they send me another good one the next day. idm working perfectly💯 Recommended

Bought this to replace my tired IDM. Very happy that it resolved the problem and outperforms the old one. Noticeable power increase and much touchier throttle! I would buy from this company again.

This idm is amazing, I notice a difference with acceleration and overall fuel economy, and the best part is this is a bit cheaper than an OEM replacement from O’ Reilly’s. I will always stick with full force when I can for parts, they never let me down and have some of the best customer service out there!
