i am not looking for any extra power so do you guys recommend the tv delete and the air intake...just remove the baffle and im good to go?

love the sites guys. my head is hurting from reading 6 hrs of posts!
good luck on having a muffler shop do it, all the ones I've dealt with wouldn't modify emissions systems for any amount of money......federal law!!!!!!

Yes, i also think running that CCV line to the atmosphere is better for the turbo. I deleted everything off my truck and i have the hose routed to the underside of the truck with a hose.

Ive seen where guys hook this line up to the bottom of their airbox, i might try this too.

Thanks mikeshauling. I did full deletes a while back and a S67Smarty me. I then did route the cvc to under the truck just as you just described yours. I thought it would be a good thing.

The only downside to the reroute to the atmosphere( under the truck ) instead of to the airbox, is that some guys say they can smell the oil in the cab. Another is, there is a chance of oil dripping on the driveway from it once its no longer routed to the tube. I havent had any smell yet, but ive only had it like this for a few thousand miles...

Up until the 6.7 the crank case was always vented to the atmosphere.

That's what I'd do, but don't want to hassle with removing the crossmember or sawzall to the stock exhaust... Especially, when I most likely will need to remove/replace every couple years for smog...

Full deletes lend more to a physical benefit also, Ive now got a ton of room under the hood to play with.

will water/methanol injection clean turbo?

My 08 2500 is used to pull a 5th wheel for work. It is coming up on 100k miles. At that time I plan on doing the deletes, Smarty, trans service with a Mag-hytec deep pan and a Snow Performance MPG-MAX injection system. I have already had a bunch of egr problems with a cracked something or other replaced by the dealer.

1) will the methanol/water clean the soot out of the turbo or should I do the dealer service turbo cleaning?

2)What else should I do @ 100k miles for reliability and longevity?

Thanks much.

I think I would have the turbo cleaned prior to deletes, then you know you are starting clean.. I am not sure what water/meth will do for cleaning the turbo.

general opinions of local wrenches is take it out and floor it blowing the soot out at regular intervals. Just doing the deletes is said to triple the life of the VGT Turbo which they say WILL have to be replaced at some time due to poor design. The drilling and cleaning port I was told was the fix for the original turbo and vent set up early 7.5 vintage. few 2008's had to be replaced, or my dealer was making up stories again. I was also told that because I put a high capacity transmission pan on my truck it voided the engine warranty? Guess Dodge is selling bridges also in Manhattan?

Aside from the cleaning port the turbo is unchanged, the reliability increased from a tuning change.

I asked this on another thread but this one looks more geared towards getting an answer.
If I remove the electronics on my spare VGT that is off the truck, can I immerse it in a degreaser to clean it? Then rinse it, air dry and reprime with some oil?

It would be nice to service this turbo off the truck if I could.

So I had the soot issue with my turbo and now I am going to do deletes... But I did take it to Dodge because they had already cleaned up my turbo once before... now they DON'T CLEAN... instead they wanted to replace the entire turbo... they said they cant even get the tool any more

Yep. My wife's 07.5 was just a month from being out of warrantee when we got the code. Dodge replaced the turbo. The service manager said the cleaning option was a band-aid fix and would last ten or fifteen thousand mile.

With the new turbo on I went straight out and ordered the Mini-Max and delete kit. Hopefully, I wont need to have the turbo replaced for at least 100 K miles.
