Help, p0299 codes

I bought a 2006 6.0 with 74K on it 3 months ago. since then I have put 3k interstate miles on it. It is chipped with a dr performance, and air raid intake. the truck runs good, (doesn't smoke )but when I tow and need to pass or climb a hill, the the boost comes up to 28-30 and rpm's increase, but it feels like it should have more power, soon after the pass or hill climb it throws a P0299 code,(low boost) it also says miss fire and 02 mon fault..help!

first off ditch the air raid intake put the stock one back on if you can the stock filter is a good one

what ever you are pulling codes with is not reading them right 6.os dont have a o2 sensor/monitor

as far as the low boost p0299 the turbo veins maybe sticking might want to clean the turbo and check the cac boots for leaks

P0299 can be over/under boost. You are a little high for a stocker. I had the same code and had to replace the turbo. Take the previous advice and go back to the stock intake.

Code P0299
(2004 & 2005 MY only) will be set if the difference between EP_G and EP_DES
meet any of the following conditions:
Greater than 14 kPa or 2 psi with RPM below 800 for 15 seconds
Greater than 20 kPa or 2.9 psi with RPM between 820 - 1995 for 30 seconds

Greater than 80 kPa or 11.6 psi with RPM above 2000 for 90 seconds

hope this helps
