blue99stroker You can use torque pro and a WiFi adapter with an android device

You want to read duty cycle and Icp. After heavy throttle for 5 seconds

Andrew Hubert I have a fuel pressure gauge on the truck, never been below 55 psi. I will have to get out my laptop and watch the pressures on the icp. Will that pull a code? I don't have any yet. Could my injectors be on there way out?

blue99stroker Andrew it sounds like you might have low fuel pressure or Icp then.

When you add fuel boost levels should come up.

Most guys see 28-32 psi with the ww2 and tuning.

Now subtract 5 psi or so from the max reading to get what your max should be with the 1.0 turbine housing

Andrew Hubert I do not have the red hose hooked up anymore and I tightened the spring on the. Wastegate. I have bellowed up pipes. If I tune the truck at all to add more fuel it doesn’t make anymore boost just egts. Sorry it took so long for me to reply. I was out of town

You need more fuel to keep that bad boy spooled up.

15 psi stock is normal but not it’s a bit laggier due to the bigger housing

mcnance865 1.0 a/r housing is stock size

You most likely have boost leaks. Search for the boost leak detector and check up pipes at collector (should get bellowed up pipes no matter what), check all boots at intake spider, plenums, and intercooler.

yan7gin The bigger housing will lowe egt but also lower boost while dropping drive pressure witch is a good thing.

But that boost is low for the WW2. I run 33 psi with the 1.15 housing with about 38 drive pressure.

I would do a boost leak test and look around your up pipe for leak.

Is your red line still hook up?

So I installed a wicked wheel 2 and a 1.0 A/R housing. I tightened my waste gate to keep it closed. the hose to it hasnt been there forever. the other end is plugged. I am curious though, I was under the impression these two upgrades would lower egt and increase boost. I was pulling my fifth wheel today and I kept getting hot. over 1250 egt and only about 15 psi boost. I was in the stock tune. I had removed my diablosport off the truck
