From what i understand you have to do both. Correct me if I’m wrong but what good is the cooler doing if the EGR is deleted. I think you have to do both the EGR delete and the cooler.

 

According to BulletProof the COOLER is strret legal the DELETE is for off the road. It is one or the other choice not both.

 

Technically speaking, tampering with ANY emissions part is a federal crime.

With that said... I've deleted my EGR valve and cooler. Gone. MIA.

BPD has a nice upgraded cooler, and if I lived in Cali where emissions testing is far more restrictive, I'd have one of those. For the cost, I figured to just delete it was my best option.

A first timer can expect 12+hrs to do an EGR delete. Have a buddy on hand to help, because you'll need it. I don't think any special tools were needed... I remember having to go get a 12pt 8mm box wrench though as I didn't have on on hand. I know the bolts/studs for the up-pipe use the 12pt hardware.

It's not difficult at all, but very tedious! You will swear a lot, and you will down a lot of beer.

 

well i look forward to the beer part. haha

 

I left my EGR valve in place because:
1. Didn't want an open circuit with the valve unplugged.
2. The valve wasn't scavenging exhaust, the cooler was.
3. I agree with Liberator that the cooler is the problem not the valve.
4. I was tired of being under my hood!

 

Another good reason to leave it plugged in is some strategies need it plugged in for the fan to operate, without the valve the fan will never come on.
