Question 01 7.3 f250 boost problems

I have a 2001 f250 7.3 turbo. I have a super chip processor and everything was working fine, now it is only getting 16psi which is stock and I should be getting 32. I put another processer on and it does the same thing. I am getting all the other advantages that the processor is putting in but not the boost. HELP ME!
Thanks

I would check for a boost leak in the CAC boots, as well as the two red boots at the Y pipe, you may have a split in one. If you have a map fooler, that could be the cause of the problem as well, it could be a false reading. If you don't, you may be defueling at 22-24 lbs, but with a stock turbo, 32 is mighty hi for boost. Fill in your sig, then we can see what mods have been done, and can respond accordingly, It can be difficult to diagnose a problem without knowing what is changed in the truck, Good luck.

Gord.

i have to agree 30psi for a stock turbo is pretty high... i get to around 31psi with everything all the way up.... make sure you dont have any leaks and if your boots have a lot of oil on them pull them off and clean them.. spray with a lil hairspray inside to help them stick to the tubes and reinstall.....

My 2000 with a superchip run 16psi. If you want more boost pull that little red wire. You may get 21psi then, but I would get a a housing a wicked wheel to get the boost up

16psi is standard for what you have
