So you’ve finally decided to ditch the stock exhaust on your ride and go with something a little more free-flowing, huh? We get it – who doesn’t love the rumble of an open exhaust? But now that you’ve unbolted the old exhaust and tossed it in the scrap pile, you’re suddenly wondering if deleting your catalytic converters was such a bright idea. Without those cats, your check engine light is on and your state’s emissions test is looming large. Is there any way to put the proverbial cat back in the bag and restore your cutouts?
What Is an Electric Cutout?
An electric cutout is a safety device used in electrical power distribution systems. It’s basically an automatically operated electrical switch that connects and disconnects a power line. The cutout senses when there is a fault, like a short circuit, and cuts off the power supply to that section of the line to prevent damage.
Once the fault is cleared, the cutout will restore power. This on-and-off cycling happens very quickly to minimize disruption. Electric cutouts are commonly used in overhead power lines and underground cables to protect expensive equipment like transformers from power surges and overloads.
There are a few types of electric cutouts:
- Fuse cutouts – Have a fuse link that melts when overheated, breaking the circuit. They need to be manually replaced.
- Recloser cutouts – Can automatically reclose multiple times to restore power until the fault clears or it locks open. They reduce outage time but may reclose into a fault, causing damage.
- Sectionalizer cutouts – Isolate only the section of line with a fault. They minimize the area affected by an outage but require more complex control systems.
- Trip saver cutouts – Detect faults but only open if the fault persists for a set time. They reduce nuisance outages from temporary faults.
By using electric cutouts strategically in the power grid, utility companies can improve service reliability and reduce power interruption for customers. The cutouts sense faults, isolate problems, and restore power as quickly as possible. With an efficient system of electric cutouts on the job, you’ll barely notice a flicker!
Deleting the 6.7 powerstroke egr delete
So you’ve decided to 6.7 powerstroke egr delete. Good for you! That exhaust gas recirculation valve is nothing but trouble. Here are the steps to remove it:
Removing the EGR Valve
First, locate the EGR valve. It’s on the intake manifold, near the exhaust manifold. Disconnect the vacuum line and electrical connector from the EGR valve. Then loosen the mounting bolts and remove the valve.
With the valve out of the way, use a gasket scraper to remove any remaining gasket material from the intake manifold and exhaust manifold surfaces. Clean them thoroughly.
Installing the EGR Delete Kit
Now you can install your EGR delete kit. The kit will come with a block-off plate to seal the EGR port in the intake manifold and a pipe to route your exhaust gasses away from the intake.
- Install the new exhaust pipe and secure in place.
- Place the block-off plate over the EGR port and install the mounting bolts to seal it up.
- Tighten all bolts to the recommended torque specs.
- Start your engine and check for any exhaust leaks. Once everything looks good, you’re done!
With the EGR system deleted, your 6.7 Powerstroke will breathe better, run cooler, and potentially last longer. No more stuck EGR valves or clogged intake manifolds for you. Enjoy the improved performance and fuel economy – you’ve earned it!
Can You Restore the EGR System After Deleting It?
Once you’ve installed an electric cutout system and deleted your EGR valve, can you restore the EGR system? In short, yes, the EGR system can typically be reinstalled if needed. However, there are a few things to keep in mind.
Reinstalling the EGR Valve
To put the EGR valve back in place, you’ll need to reattach it to the intake manifold using the original bolts. Make sure the valve is clean and debris-free before reinstalling. You’ll also need to check that the EGR tube or pipe is properly connected and sealed.
Reconnecting the Electrical System
The EGR valve requires an electrical connection to function. Locate the original wiring harness plug and reconnect it to the EGR valve. This will provide power and allow the engine computer to control the valve.
Reprogramming the ECU
Simply reinstalling the EGR components may not be enough. The engine control unit (ECU) likely has adapted to operating without the EGR system. It will need to be reprogrammed to recognize the EGR valve and properly control it. This is best done by a certified mechanic with the proper scan tool to reset the ECU.
Double Check for Proper Operation
Once everything has been reinstalled and the ECU reset, start the engine and check that the EGR valve is functioning properly. Have a mechanic test drive the vehicle to ensure there are no check engine lights or performance issues. It can take a few drive cycles for the ECU to fully adapt to the reinstated EGR system.
If all goes well, your vehicle’s emissions system should be back to operating normally with the EGR valve and related components working as intended. However, some performance gains from deleting the EGR may be lost. For the health of your engine and the environment, keeping the EGR system functioning is best.

You’ve now learned the steps to safely deleting a kit using spelab and how the process works. While the kit and all associated files will be permanently deleted, at least you now have the knowledge to avoid accidentally deleting a kit in the future. And remember, once a kit is deleted, there’s no way to restore it, so be extremely careful when using the delete option. But don’t worry too much – with some practice, deleting and re-creating kits will become second nature. Now go forth and customize some kits, just promise us you’ll be careful with that delete button!
