C15 acert bxs problem!!!!

my friend has a bxs and he is getting 45 pounds of boost

 

When my bxs was a 475 1850 I got 45-47 psi. Now that its a 550 with the heavy haul it will go to 60.

 

I asked a buddy and he gets about 45 lbs of boost.

 

when my MXS lost power and was a laggy pig it ended up being 2 junk turbos due to an exhaust sleeve. If it ends up being the same problem you can have yours rebuilt rather than buying new ones.



It could also be a cracked bellow but with the amount of boost your losing I would think you could hear that, I know I could.



On a side note with the turbine wheels both chewed up and the PDI Stage 1 tune.....it ran like it did stock without the tune. So I can only imagine what a pig it is with a stock ECM with low boost.

 

I wish those bellows were made out of a little heavier gauge metal. I got one that has a little crack in it. Atleast its the easiest one to replace.

 

Your going to where I take my Cat to get worked on, if Andy works on it, it will be right.
Troy is the shop foreman is a great guy and will work with ya.
Tell'em you heard there was a red Pete that got worked on there and came out running like a raped ape. Andy and Troy will know who your takin about.

 

MXS 475 I drive will make about 42 pulling a grade in 7th direct. So I would say CAC leaking maybe the tubes for it or something in the fuel system.
