Boost

Im sure there is a post on here already about upping your boost level on the stok turbo I just havent found it yet. Is this possible? How? Not wanting to up it alot. Mabey take it up to 28-30 lbs. Is this too much?

what kind of mods are you running? the stock turbo can achieve 30psi but your going to need a chip or tuner and even then its already into the area where its prob doing more harm than good..... what kind of boost numbers are you seeing now?

I have a afe stage 2 intake, 4" turbo back exhaust, and an dge evolution. I just notice on the 100 hp tune I smoke ALOT. I was thinking if I could pick up boost a little bit I could make a little more power with all that wasted fuel. i dont want to hurt my truck though.

With the ported compressor housing or Wicked wheel and also a 1.00 A/R turbine housing you should be ok pushing 25-28 lbs if you also have an adjustable wastegate or turbomaster wastegate controller. However if you do tighten the wastegate up and you are not surging but you as well do not see more than say 25 psi I believe that is all the air that the turbo will push. If you try and make it boost more its really just making the air hotter and you wont make any more power. But like mentioned earlier what boost are you running now and it will be easier to tell you what you can do to get a little more.

this is how i think about it.. by the time you end up buying all that stuff you are more than 3/4 away from a 38R. might as well spend a lil more and get a better turbo
