Anybody recommend a tuner for a STOCK 08 6.7? Emission system friendly?

 

Smarty, but I also suggest you delete the emmission for when you need them which is not on a daily basis unless you are paranoid.

 

not paranoid, just dont want to deal with it. local diesel shop told me today that he could get a 15k fine for doing the deletes on my truck, and also there is news that emissions testing coming back to MN in the near future..

 

That would really suck

 

Stock is the way to leave it if your wanting to keep your emissions equipment. The extra fuel will cause the DPF to work harder, which will cause more regen's and worse fuel economy. You also could cause the DPF to fail if you tune it and leave the DPF on there.

So I would either tune and delete or leave it stock, 100% stock.

 

Okay. Could you guys recommend some upgrades I could do to a stock truck? I'm thinking I'm limited to cold air intake and larger exhaust...which is fine I guess.

 

No need to upgrade the exhaust if not doing a full delete the cat and DPF are still the limiting diameter.

 

You won't see any performance incerase out of it, nor mileage. There isn't much point to do anything to a stock truck, they breath as good as they can.

The only thing that may be a benefit would be a grid heater relocate. If you put the grid heater before the EGR inlet it does 2 things, 1 is flow better and 2 is won't get caked up with soot and block more flow.

Something like these two..

Otherwise if you want to do anything look into fuel and oil filtration.

 

So a FASS 150/150 and a amsoil bypass system would be some worthwhile upgrades in this case?

 

If you are not going to delete, leave it stock and work it hard.

 

I would do a FASS Platinum into the OE canister, and the Amsoil bypass.

 

Like Blake said, if its stock, work it hard and often. I had some issues with not working it hard and that stupid dpf plugged up ALL the time. Now, after some emissions "adjustments", the DPF does not plug up at all, maybe its because its sitting in my basement?

 

Not necessarily true.. The Stock program for the Smarty disables the EGR system which is about 50% of the soot produced under low load, idle situations and regenning of the first Oxidation Cat. That and advancing the timing will actually produce less soot (less DPF contamination) and should even out for power vs. soot produced. I saw no increase in the amount of regens with the Smarty on stock exhaust vs. without the smarty.

I have seen a truck with just the DPF removed and when the EGR is working, the soot out of the pipe is ridiculous. It looks clean on the outside, but inside its pure soot. With my Blacktec I rarely get any visible soot even on the SW5 setting.

 

Interesting.

I don't know how it is on the 6.7 since the pistons are differnt, but the more timing I run the more soot that gets into my oil.

But if you can shut off the EGR on a stock tune I don't see that as being bad. But if the timing drops the EGT's too much I still think you will have more active regens as the DPF will have a very hard time going into passive regen (which really won't happen anyway's unless you are towing up a hill all the time).

 

Yep plan too. This truck is not my DD but do occationally drive it to work which is a 10 mile trip. Its main purpose is the long haul travel vehicle and a tow rig for my Jeeps.

This is exactly what I was thinking. Any reliablility concerns with the FASS at all?
