Understanding the 7.3L Powerstroke
The 1999-2003 7.3L Powerstroke engine is a legend for its bulletproof reliability and raw torque, powering Ford Super Duty trucks through heavy towing and off-road abuse.
Stock, it delivers around 250-275 HP and 500-525 lb-ft, but emissions gear and airflow limits hold it back. Enthusiasts upgrade with 7.3 parts performance kits to overcome these, gaining 100+ HP while improving fuel economy.
Whether you're dealing with a sluggish turbo or fuel delivery issues, our 7.3L Powerstroke parts address common pain points like injector wear and exhaust restrictions – all while extending engine life in high-demand scenarios.
7.3L Powerstroke Key Performance Upgrades
Maximize your rig with our curated 7.3 aftermarket parts. Start with turbocharger upgrades: Swap billet wheels for quicker spool and reduced lag, ideal for towing.
High-flow exhaust systems cut backpressure, adding that deep rumble while boosting efficiency. Cold air intakes and intercoolers pull in denser air for better combustion, delivering noticeable throttle response. Upgrade to performance injectors and lift pumps for reliable fuel flow under load.
Don't forget tuning chips and programmers – like our 1999 7.3 Powerstroke tuner, 2000 F250 7.3 tuner, or 2001 7.3 Powerstroke tuner – for custom maps that unlock 50-150 HP gains.
These 7.3 tuners (including 99 7.3 tuner, 1999 7.3 tuner, 2001 7.3 tuner, and 7.3L Powerstroke tuner) offer shift-on-the-fly convenience and long-term savings on fuel and maintenance.

So far so good with my AFM delete on my 2017 Silverado
5.3 with the factory sport exhaust. I haven’t driven far yet but I can already feel the difference at low speeds being my V8 mode is always on now. The light goes off after shutting my truck off so no battery drain. Before my truck had like a flutter sound at low rpm at speeds around 40mph I guess that’s when my V4 mode was kicking in. But instantly that’s gone now also just slightly pressing the gas pedal now the engine comes alive quicker than before. I’m very satisfied so far and for the 40s $ price range. I first looked at one for around 300 bucks. 5 stars I’m impressed thanks

Ordering process with short, sweet, and to the point; exactly how I like it. The product arrived when it was supposed to. I would definitely order from this company again.

Great overall

it was easy to install and great delivery, got it within 4 days of ordering
I just received the fuel management delete module and let me tell you how happy I am with this thing… all it was claimed to be… very fast shipping…AAAA+=++!!

I know now that my Chevy 5.3 will not fail after 90k miles as the stupid 4/8 change system has been eliminated. Super easy plug and play on my Silverado.

Product came i plugged it up and it works the way it states i recommend everyone with a5.3 and 6.2 get this ASAP

EGR Delete Plug Kit for 2010-2024 Cummins ISX 15 CM2250 CM2350 Plug Kit

Nice!

Stops the motor from kicking down to 6 or 4 cylinders which is supposed to add years to the motor. Thanks

Even before I purchased this, I was experiencing minor hesitation issues without the Check Engine Light. Also since I purchased this truck 4 yrs back, as I type this out, I had to replace the EGR within 3 months. Other vehicles owned with EGR have not experienced this level of issue when the code was checked on the CEL. Now I have been living with the EGR issue in recent months this time, until I determined what steps I wanted to take to permanently resolve this. After weeks of searching, and no real difference between everyone I looked at on the web, and it kinda was a no brainer, spend the money on a new EGR valve, or spend the same amount and eliminate, in essence bypass the valve emission system all together, especially since this truck at 35 years is not required emissions check in this state at 25 years.
My apologies for taking this much time to respond. The block off plate in this kit for my truck is not necessary. The plug on the sensor was removed, the slave was set, the wiring harness secured to a location out of the way of any issue, CEL cleared. After 3 days with some minor hesitation issues still existing, it was determined the vacuum line originally left alone might need to be plugged. To conclude since the vacuum line was plugged there were no signs of hesitation from standing start or any driving conditions requiring further increased pressure on the gas.
Thank you I am pleased with the response, the resolution of the EGR issue, full stop...

I bought the kit with the up-pipe to delete the EGR cooler feed inlet from the exhaust instead of the small disk that blocks it off. My mistake but, don’t get pinched like I did.

I run a small business, and it ain't always easy. Sometimes the best you can do is correct mistakes when they happen. I had a problem with the two AFM disablers I purchased (purchased together).
I contacted EGR and they acknowledged they did have an issue with some of them. They immediately sent me two replacements and the replacements are working fine.
In my opinion, that's how it should be. Thanks.
