Bellowed uppipes don't use donut gaskets so no boost leaks.

The K&N element should be avoided in turbo-charged applications. The initial filtration efficiency is not high enough to protect the compressor impeller. Almost no one uses these in the offroad world as they just can't stop the dust...40+ year old tech.


There is an overboost code that reduces the cycle time of the IPR. The result is a slower gain in acceleration, not a reduction of fuel. The way to see if you are setting this would be to scan for the code. I run a MAP Pressure Relief Valve on all our builds. Some tuners can turn off the check engine light but you still have the issue.

What is your max boost? A SD 7.3 after 22-24lbs will pull back the HPO.
