EGR delete and LAWS

Alright... the EGR delete is obviously against the laws with emissions. I know the 2006 and later are not held to the strict emission laws with smog checks. My father was telling me that I better not get the EGR delete because they are going to make us get our equipment checked with emissions in the future and they will find out our EGR coolers are deleted and force us to have to put one back in. Has anyone else heard of this being true? I read now they are making these heavy duty EGR coolers now to replace for our old faulty coolers. Can anyone elaborate on this issue for me? I want to get an EGR delete, but my dad says I better get the bulletproofdiesel upgraded cooler so I don't get banged for emission tests in the future...

This is a matter of personal choice as this is America. true it is in violation of federal EPA law to tamper or otherwise render inop. any pollution control device on a motor vehicle, but it is up to you to decide. one thing is pretty certain, you stand a high chance of experiencing a failure if you leave it alone..

You can get a full egr delete for your truck and still have the valve in place. You just need a tuner such as a SCT to disable it. Thats what I will be doing shortly.

I know of 2 6.0 powerstrokes that had the egr delete done. They also both melted the engine because the egr delete raises the eg temps 200-400 degrees. So if you do this, you better monitor those eg temps really close because down here where the temp can reach triple digits in the summer the egr delete can be more costly than the egr cooler going out. Just my 2 cents.

EGR delete should lower EGT , not raise it.

I got taken out by a Hyundai...it's not funny...now I look like Stump, but taller

It is illegal. But since Adam isn't in jail yet, you are probably safe for the time being from the EPA police. If you fail an inspection, you will have to install an EGR cooler to pass. Ryan is correct about Combustion Temps also. If you delete, tow, and live someplace with more hills than florida, it could become an issue.

Also EGR cooler issues almost always stem from other issues. So in treating one symptom, you could be covering up the symptoms of another disease until it's to late. Make sure either way you have it checked out fully.

EGRs lower COMBUSTION temperatures. NOx are formed at high COMBUSTION temperatures. This is different than exhaust temperature. By doping the cylinder with inert (yes exhaust is mostly an inert gas) The combustion flame is slowed and won't burn as hot.
