I know there are some diesel drivers on this board. I'm looking to install a DPF delete kit on my 2008 Duramax. Has anyone on here done this? I have been doing some research on the topic for a few days now, and I’ll be honest, I'm not sure exactly what I need. I do know that I don’t want a tuner that’s going to be adding 200 HP and 300 ft/lb’s of torque or some other crazy numbers, this isn’t a race truck, and I'm not the type to drive by little go-kart hybrids and smoke them out. All I'm looking for is a tuner that will reprogram the computer to bypass the DPF, have an economy setting and a towing setting. I do have a 40’ 5th wheel that we use about 10 times a year, so a towing setting would be nice.

I have found a few kits that include the DPF delete pipe and a tuner, but those look like the run in the $1,000 -$2,000 range. I have also found that you can buy the delete pipe separate for around $250, and a separate tuner from as low as $300 to as much as $1000.

What’s the difference between the $300 tuners and the $1000 tuners? Why would I spend $1,500 on a kit when I can buy everything separate for around $600 if I go with a cheaper tuner like an Edge?

where are you located?

I live in Aledo, just west of Fort Worth in Parker county. We don't have emissions test, only a $20 state inspection fee.

With the EPA cracking down on this sort of stuff recently, it's getting harder and harder to find tuners at a decent price that will allow you to delete. I have the H&S XRT Pro and really like it, but I bought it before the "crackdown" began. The current versions are "street tuners" and they don't allow you to delete anymore. If you want to delete you'll have to find a vendor that still has some of the older ones in stock and you'll have to be prepared to pay a premium for them. I bought my XRT Pro with a new downpipe and DPF delete pipe back at the end of 2012 from Rollin Smoke Diesel for $830. You'd be hard pressed to find it anywhere close to that price now.

If you do delete then be sure and keep your old parts. I'm sure the day is coming when you'll have to put them back on.

They'll talk you through which tunes are best for what you need. "IdahoRob" is a well known dmax tuner that puts out quality, safe, and clean tunes. I wouldn't mess with just a delete pipe either, you should be able to get a dp back 4" exhaust for 350-400 and it'll get rid of your cat also.

ETA: Have your EGR blocked also while you're at it.

Hoss - would it be better to just buy a tuner with an economy setting and leave the DPF on? I that possible? Right now I'm thinking of going this route, leave the DPF on and just put a tuner on and see what that does.

I'm tired of driving down the road getting 17 MPG and just watching it fall like a rock to around 13 or so while it goes thru a regen once every tank. For me to even get 17 I have to drive like my grandmother, anything over about 67 and I'll be lucky to get 16...

Meggy - yeah I was thinking of doing the EGR delete as well, just not sure if I can afford all of it at once. If I did a true turbo back exhaust I think I would be a bit more nervous of getting busted, taking off the DPF is one thing but taking off the cat and the DPF might be a little much. Thanks for the link!

I wish I got 17. Or even 13.

Whether to delete or not is entirely up to you. You can certainly tune the truck without deleting. The H&S XRT Pro street version for your truck has four tunes: Stock, Tow (40 HP), Street (80 HP) and Performance (120 HP). And then there's also the option for custom tuning if you have specific goals in mind. The possibilities are endless.

Deleting will obviously cost more because you'll pay more for the tuner as well as the exhaust components, but it has its benefits.

Right now Texas doesn't require emissions testing on diesel powered vehicles, but it wouldn't surprise me at all if that changes in the next few years.

So I guess this answers my question, I can't just go buy a delete pipe, put that one and them buy a genaric tuner. I have to have a tuner that is specifically for/ or able to bypass the removed DPF?

That's correct. It has to be a tuner that specifically allows for the DPF to be deleted. With the older race tuners you input whether your DPF is present or removed and it tunes your truck accordingly. With the new street tuners that "removed" option isn't available anymore. So, if you want to delete you have to find one of the older tuners that allows for that. Otherwise you'll throw codes and send the truck into limp mode (or dead mode...I don't know what Chevy's do).

They go into limp mode, mine did this a few years ago and I thought I was going to have to replace the DPF. It was telling me the filter was clogged. I got lucky it turned out to be a MAF sensor that was dirty.

Thanks for your help!

Call Amanda or Jason at the Ranch Hand store in Irving. Our stores do this all the time. They will know exactly what you need.

I have 2 that are done with DPF delete, I have 4" straight pipe from the turbo out the back. Because of the turbo it is not loud and helpd it breathe a lot. You do have to find a tuner for DPF delete so it won't put you in limp mode, but you DO NOT have to jack it up a bunch of HP. Unless you are drag raging or truck pulling it does not help, in fact it can hurt pulling because it causes the turbo to run hot. Economy mode or stock keeps things good and you get better mileage and no regen!!

The more I read, the more I'm leaning towards just buying a tuner and leaving the DPF for now. There is a company called www.powerupdiesel.biz that has a product that's called EZ Tuner. They claim to increase the economy by 4-7 MPG. They also have a 6 month money back guarantee. They have tons a good reviews on their site. If it doesn't work I'll send it back!

Or if you just like your 9,000 lb truck to be fun to drive. I don't race or compete in any way and I can't stand trucks that blow tons of black smoke, but I'm pushing around 475 HP at the rear wheels and it's a BLAST to drive.

Also, horsepower isn't what burns up turbos. Not knowing what you're doing is what burns up turbos. Your turbo will be fine as long as you're not trying to hot rod it while you're pulling heavy.
