Not arguing against the "traditional" justifications for a delete. However, in reality there is no imperial evidence that shows a WELL MAINTAINED (not hot rodded) truck in stock form = less engine life than a deleted motor. And BTW, I was always a fan of deletes, especially with older versions where the emissions systems where rather new (6.0 and 6.4 especially along with Duramaxs and Cummins, etc).
However, I would like to bring up some articles that argue or warn against it so others can look at both sides and make an informed decision. Also, the EPA is heavily cracking down on aftermarket tuners in just the last 2 years. Scares me a bit. Plus you do take a hit on aftermarket value if your truck is deleted (I dont plan on selling mine...driving it into the ground).
Some opposing articles that warns against it:
Every single day we receive emails, phone calls, and live chats with clients who want to perform emission deletes on their trucks. All these clients have the same problem – repetitive, costly repairs on their vehicles, and they are tired of it. I genuinely sympathize with them; a lot of these...
Keep your truck running the best way possible!
Diesel pickup tech questions regarding legality of DPF/EGR deletes, cause of P0401 fault code, and best winter tire choices.
Overall, I completely agree with reasons why to delete. I am just not 100% anymore they outweigh the con's. And the EPA risk is becoming much higher as they crack down on aftermarket companies.
My plan is to sit and watch at least for another 30k miles or so. Let my warranty period end and see how these newer trucks are doing in stock form with 200k+ miles.
