Sounds good I'll give it a shot. Would suck to order these parts and it not function. So if I unplug the throttle valve, if it doesn't go well can I plug back in and just take out the butterfly? I've heard of guys doing that but can't find out any info why or what that does.

 

Will running simmer lead to the dog getting plugged up? If you are running sins will it show up on the computer and lead to a warranty issue?

I'm getting close to the time when things start to fall off, but I'd like to sample it some before committing myself permanently. I plan to unplugged mine this weekend when #1things son is home.

 

This is a question for Blake,

Is a throttle valve delete required once the deletes are done?

Can I just unplug it? nor not worry about it.

I know it is recommended to do, but what does it gain? piece of mind?

 

Its not required to delete, just unplug when running a programmer, well on the 3rd gens anyway. On the 4th gens you dont have to unplug anything at all under the hood with the Smarty or the H&S. Both command all functions to null. This is how my '11 is set up.

However, like you said, piece of mind. If deleting the EGR and Cooler, might as well yank that thing too, its only 4 bolts.

In fact, when I do delete mine Im gonna get a new intake that does both.

Having a hard time understanding why. A lot of trouble for so so results and with all the codes you are going to throw your warranty will be in trouble anyway. Get a tuner.

Hi Sir Blake, Is there a HP gain with the manifold or is it just a "cleanup" thing?

 

HP gain would be really really negligible. Should reduce EGTs some. Really nice cleanup unit too with ports available for gauges and water/meth etc.

 

OK so i took a 680 mile trip yesterday to get a bed installed on my truck. I unplugged the egr, going there i got 15mpg, coming home with the bed i got 14mpg. Going there everything was great. Coming back, when it was shifting through towns it was feeling and sounding like it was trying to regen and making noises that sounded like pressure. I also noticed i used 20% of my urea coming home which is only 340 miles. So i plugged the egr back in when i got home, i gotta go to the dealer in a few hours to get my plates. Ill probably leave the egr in till i can delete the dpf and stop the regen. I'm gonna unplug the urea first and see how it runs, cause ill bet it'll use a lot when i delete the dpf.

Thinking about removing the butterfly from the throttle valve, maybe that was the noise i was hearing? And at least if it does revenue its getting more clean air not just exhaust.

 

I'm sure your going to trigger more flags with the hundred or so emission code clears. Just take your truck in for emission recalls if you need warranty work. The reflash will remove the tuner traces. After the recall stuff, go full tilt on the required driveline issues.

 

Not sure how factual this is but I talked to the service manager about doing deletes and tuners and he said that (he referred to diesels specifically) that when they connect up to the trucks the info get's sent directly to dodge and if there are signs of a tuner the warranty gets voided instantly.
He and I have talked about possible mods for my Challenger and was pretty open to tuners and mods at the time. He seemed sincere about the trucks.

 

So I'm thinking about deleting the cat/dpf, put the sims on that won't bring on the cel. I have the egr all plugged in still but took out the spring and the ARM that pushes the rod to let the regen air flow back in. So no codes, and don't loose the 40 or so HP by keeping it plugged in. So I don't want the cel on. But for some reason I'm going through urea like crazy.

 

Well with sims your still gonna get a check engine light. Not to mention having to deal with the urea delete. I hate to tell you this, but, your gonna need a programmer to make it run right, or leave it stock.

The urea usage, my speculation would be that it is still going into regen and thats where the urea is going. Now why is it going into regen, I cant say. Maybe someone else will chime in.

 

Oh cause I thought you said those 100 ohm sims won't turn on cel, but will still regen and the 330 ohm sims won't let it regen but will turn cel on?

 

Let me back up. True with the 300ohms you will get a cel. You will also probably get a cel for delta pressure. If you have the egr unplugged toss that into the cel grab bag.

Bigger issue is gonna be finding sims. Another member here is on the hunt for some and H&S told him they stopped making them. I did a quick search yesterday and didn't see any for sale. Existing stock might be the only sim option short of making your own.

Here's a thought as to why the high urea use. Urea is used to control NOX emissions. Nox is higher with higher combustion temps. My understanding is that the heavier the load on the engine (higher egt's?) the more urea will be injected to control Nox. Now, your sims are telling the ecm the truck is generating enough heat that it doesn't need to regen, but at the same time they are also telling it that it must be putting out a bunch of nox emissions.

kind of a slightly educated guess. But I could be completely off as well.
