it is plastic, so that means its 6.0? Sweet...
So what mods should i do...I have the turbo, 6.0 IC AFE intake, and 4" exhaust....not sure if i have a 4" DP or not...if i dont maybe get a 4" DP and the bellowed up-pipes since ill have everything torn down anyways? also what is the point of eliminating the EBV? As i understand it this is just a matter of gutting the pedestal....Lets hear some suggestions!

yea ccv mod is definitely the next thing up...one question though, would you advise routing it back into the air intake or just into a trap and vented to atmosphere? My inclination is to route it back to the intake.
I still dont get the point of eliminating the EBPV, could someone explain this?
Also, if i dont have a 4 inch DP would it be a benefit to get a 4 inch DP and the bellowed up-pipes? or would I be fine with a stock DP... Would it be easier to buy one of the pedistals without the EBPV stuff in it? Also if i'm going to pull the turbo off to do the up-pipes is there anything else I can do while i'm in there? I already took care of the UVCH issue. Im looking to get the best performance without going overboard on cost or parts.

if you do the ccv mod, the point is to run the blow by some where other than your intake. if you run it back in to your intake you gain nothing.
eliminating the ebpv will give you a little bit free er flowing exhaust.
a 4 inch dp makes a nice change in the way the truck feels compared to stock.
if your up pipes are not leaking why are you wanting to change them? from what i know your not going to change much going with bellowed unless you get them ceramic coated.

My CCV is routed to the atmosphere right behind my rear axle. But some are starting to route it to a filter box and then back up to the intake this way you don't see the smoke at your rear fenders. I may look at that soon.

I would be routing it through a filter of some type, most likely homemade, then back into the air intake. The uppipes I would be getting ceramic coated, because if i'm gonna spend the money i might as well get it done the right way. I will look into the down-pipe, for some reason I think I have a 4" one, since he put a magnaflow turbo back onto the truck. Doing the muffler delete either later this week or next week
Hook it, I'll pull it.

I have the same turbo, TN BB. TN did make a none BB turbo a few years ago. I bought one of the last turbos, so people say they were the best. I can get 35# boost, no problem. I have not had a problem with my turbo, but the problem some people had was oil dripping out of the tail pipe. I think that was with the none BB turbo. My turbo did good on the 1/8th mile track at RRE.

so i think the issue with my boost might be that there is an OBA and the previous owner might have taken the reading for the boost gauge from teh MAP or after it, which would mean it is not accurate. This is something I will be looking into and possibly correcting. Anyone got advice on where the boost gauge might be plugged in? I have no idea what I am looking for as far as in the engine compartment, so any help would be great. Pretty sure i will be doing the AIH delete soon and putting the boost reading in that spot.
Thanks for all the help guys.

O..another question, does unplugging the red tube from the wastegate oin the turbo make a major difference? What is the purpose of this? This was another thing that was done to the truck when I got it and then i put it back on when i realized thats where it was supposed to go. I have seen that it has been removed on some other turbos, but I have no idea what the purpose behind it is.

The OBA should be between the spider & MAP sensor. The boost gauge is usually teed into the line between the spider & OBA. That way, it sees the real boost, but the MAP sensor on sees the boost the OBA lets through. You can also delete the Intake Air Heater and use a tapped plug for the boost gauge. Here are pics of both:

What injectors are you guys running with this turbo and seeing those highter boost numbers? Is the truck empty or under a load?
I have this turbo with a dp tuner and stock injectors and can only get 28 out of it. The up pipes have been replaced as well as my boots. There are no leaks to the turbo. exhaust is a stock down pipe into a 4" magnaflow exhaust. I was told that if i went to a 4" dp that we loose bottom end.

stock injectors, on my highest tune i can hit about 32 on a good day. From what i've found these turbos are hit or miss, either you get a great one or you get a **** one...oh well looking like i have a good one

When the PCM sees a cetain level of boost (I don't know what that level is) it opens the Waste Gate solenoid and pressure is sent through the red line to the wastegae actuator and the wastgate opens to dump boost. The green line dumps excess pressure not needed by the red line into the intake. This is to prevent damage to a stock turbo. Some take the red line off and plug it to gain extra boost.
