idk ill have to check and how do i attach it?

I would just attach it using one of the boots. So whatever diameter the boot is, that's the size PVC you want. I used to have a picture but I just looked for it and I must have deleted it.

See my orange boot, I would attach it to that or go further and attach it to the intake boot. Whichever you want.

ok thanks :tu:

boost seems low to me???
 

Where's the best place to get to see if the up pipes are leaking
Oh and now the highest boost I see is 15 so whatever is getting worse is it normal for it to drop a psi before it shifts?

Just take a flash light from under the truck and look up toward the turbo. Or look back behind the turbo from above. If you see black soot, your up pipes are leaking.

Other then that check for boost leaks like James showed earlier.

Is your truck an automatic? It will drop a little during a shift but not much. If its a manual, You start back at square one every time you shift.

Ya it's an auto jw and got the stuff just got to put it together and check it tm.
Would it be easier to see up pipe leaks from under the truck or above?

I'm in the same boat as you, just hooked up a boost gauge finally and found I'm only making 5-10psi. Picked up a manual gauge and confirmed it to be correct.

You can make a boost leak tester yourself with some Fernco Plumbing couplers, car tire valve stem, and a pvc endcap from a hardware store. I've done this plenty of times with my turbo cars. Just make sure to regulate the supply going in.

Ya for air going in I'm going to use a bicycle pump with gauge cuz I need one anyways ha getto I know but it should work if not got a friend with an air compressor

You will never be able to make enough volume with a bike pump. Your going to have leaks past the valves, rings and such... Need a compressor.
