My exhaust is all welded. I replaced my leaky up pipes with the new bellowed ones so they are new. How quickly does soot show?

As long as the engine is clean it should only take a few drives..

tighten the wg all the way down. if you cant get more boost then what you have now then I would go over every connection and intake runner with soapy water and pressurize the chit outta it. unless tuning is limiting it.....

Pumped it up and found two bubbly leaks at the spider and another on an IC pipe. These small leaks can cause that much loss of pressure just blows me away.

Alright waste gate is fully closed. Boost leaks all fixed...still only getting 28lbs. Ideas???

28lbs on the economy file or the max power file?

how are you monitoring boost?

Stand alone sending unit to gauge that is inline of the MAP sensor. No boost fooler is installed.

My DP tunes would only make a max of 26lbs until I installed a boost fooler. I make 38psi now.

this!

you need a boost fooler. I dont care if it is tuned into it or not. plum in a boost fooler from riifraff or the same kind of whoever you choose.

Matt @ Gearhead said no boost fooler as it wouldn't allow the MAP to see the 25psi to allow full fuel

You can adjust the adjustable boost foolers to see 25 psi. My Dieselsite fooler allows 22psi +/-

Matt it is on the econ tune. I am hesitant on cranking it to the max as the waste gate is tightened down fully and my EGT's in that program still run 750-1000 highway.

Something isn't right but 28 psi in the economy tune at wot sounds about right

Even in the tow program I can pass 1200 degrees when getting on the highway. I did find that the old waste gate solenoid tubing rubber ends are leaking just a little.

Could that cause issue?

Anyone remove their solenoid and tubing as I don't need it anymore?

or just plug them off.

If you have Matt's tunes there is something not right. No way would you get that hot in anything except maybe the race tune and.then it would be under heavy throttle.

You also do not need a boost fooler with Matt's tuning; it's been that way for years. He was the first tuner to figure out how to tune the map sensor.

pilot4life · Jun 1, 2014

Could that leak from the waste gate tubes be enough to cause this much issue?

Only thing else I can think of is my exhaust is still leaking from somewhere but I'm not sure how with the bellowed up pipes.

I'm wondering if your up pipes are misaligned with the back of the turbo..... it's easy to do...

pilot4life · Jun 1, 2014

I thought there was only one way for the bellowed up pipes to go in?

And that pin in the collector aligned the up pipes with the turbo?

When you've done your boost leak testing...how many psi have you pressurized the system too?

The reason I ask is if you're unable to make more than 28 psi....and should be making more like 35-38 psi....and don't have any signs of soot indicating a drive pressure leak....and you have high egt's... than you've gotta look hard for a boost leak that's only occurring over 28 psi IMHO.

The good thing is you should be able to hear/find it fairly easily at 28+ psi
