turbo issue

ok so im having a low boost issue with my truck that started after doing studs,ccv,smoke switch,stand pipes, dummy plugs, stc fitting. i only get 22-24 lb where before i would get 34lb. anyway my ? is im kinda thinking it might be turbo related so i was looking at a 68mm powermax turbo and with my mods now can stock injectors feed that turbo without issues. i run eric's tunes and know i would have him rewrite them for the turbo, but can i do turbo now and add an airdog and a set of 190 sticks later?
thanks
mike

It's turbo related alright, it's called a smoke switch!

Have you tried cleaning the turbo? Have you checked the IC boots for rips? Also look at the up-pipe/y-pipe flex joints. Don't forget to check the MAP hose and fitting to intake for clogged up or damaged hose.

^^^ Yup Yup Yup! If you are not getting as much boost, you probably have a leak someplace, or potentially your turbo needs to be cleaned.

no leaks. we pressure tested all the ic piping and the intercooler. we cleaned the turbo 12000 miles ago so it should be good but we are going to look at that also.

Have you looked for leaks around the y-pipe, specifically near the bollows? they are known to crack whe removing and reinstalling the turbo.

The powermax is not that much bigger then the stock turbo and I run one with stock sticks you would be fine. But I think you should look at you y-pipe like the only guys said I had my y-pipe leak and you could not hear it.

Yeah, take a small mirror and look around all the bellow on the y-pipe for any soot residue. That is a tell tale sign that you have an exhaust leak.

I argee with everone,but I would also check the drivers intercooler to intake if you have a pastic pipe.Also check the line coming for driverside exhaust manifold for your sensor for vgt vane refenance for your ecm,make sure its's not clogged.I would also look at your intercooler to make sure it didn't bust open somewhere.Good luck.

we pressurized from the turbo to the intake with no leaks, so all boots and intercooler is fine.
