Elite Diesel EGR Delete w/ WasteGate HELP

I just recently purchased a EGR Delete/Wastegate Kit for my 2008 6.4L.

I cannot get it to have any effect on my boost or back pressure.

I have tried turning the unit clockwise from the start two turns, as well as well over 8 or more turns (turned in as much as I can without exerting a lot of force).

Neither setting seems to make any difference.

Points to note:
- the most EBP I have seen (off of my mini maxx tuner) was 56psi.

- I am tuned on the middle of H&S’s tunning (the mild, allowing up to 250hp)
- on street and performance, it is VERY easy to get to the defuel of 38-40PSI boost (have not set the defuels higher)

- as far as I can tell the unit is plumbed in correctly
- a boost line comes from the block off plate to a T.
- one side of the T goes to the regulator (that I can turn to adjust)
- the other side goes to what I believe is the bottom of the wastegate
- from the regulator, a line goes to the top of the wastegate
- this all assumes that the black part of the wastegate is the top, and I should note it is hard to see, but am 99% sure this is where they go.

If you could let me know your thoughts on this. Right now I have the unit turned in clockwise about 8-12 turns (again as much as I could turn it without exerting lots of effort...... it does get harder to turn so I assume I am having effect). I am guessing that I am just not generating enough EBP to open it, and my goal for this is a safety device.

What caused me concern however is in the forums (I have read about this for at least 8 hours combined), if you turn it in enough, the truck should not build boost very well........ I cannot replicate that condition, and as such am concerned something is wrong.

Please let me know your thoughts.

p.s. Truck is running great, just trying to put the final touches on this 1.5year process.

From what you are describing, you have it plumbed in right. You need to try a higher tune and see if you go above 70. You want to regulate it down to about 65ish

I guess that would mean going to next tune family on the mini maxx (the Hot Damn I believe).

I would be hesitant to do this, as the work I have done:
- S&B intake, Sinister Coolant Filter, CAT & DPF delete, Elite EGR delete w/wastegate, and a Titan 51galon tank........ have all been done in the interest of fuel economy/range, and longevity.

Going to the Hot Damn, would probably cause me too much stress. So in your opinion I need to generate at least 70psi of back pressure to have an effect on this wastegate, even with it turned in as much as I can without applying force. This would be good news I suppose, as if something ever spiked, it should let it out where I have it set to, and hopefully save me a repair.

Thanks for your reply.

IMO you didn't even need a wastegate. Lot of money for something that isn't going to be used really. Tuning on these trucks have came a long way and in tuner,dpf/cat delete/ intake form backpressure isn't really out of hand. You would have been better buying a downpipe and CAC Pipe/ elbow. But that being said. I am pretty sure the wastegates come with all the springs installed and I am not so sure on what the spring ratings are.

Try swapping your regulated line to the side port and your full boost line running to the top of the gate

LOL.

I struggled with the WasteGate (also got the new pre-welded downpipe).

But, figured I would go for it, as I will eventually do more to the truck as I learn and get the money. Cheap insurance I thought.

From this point my plan is to replace whatever breaks with the best when/if it breaks. Hopefully that is quite at of miles down the road though.

Thanks again for your advice.
