I didn't have any issues understanding. So my runs are consistent boost wise. Although I think my Innovate gauge might read a bit lower...maybe 10's? we just got it working so I need to check that. The issue with duty cycle was a kinked vacuum line which is why boost gauge wasn't working, and FPR wasn't raising pressure. But duty is still 70%.

What are folks setting idle fuel pressure to? 41-42? Or more like 52? CJM says 1050's are for cars making less than 700WHP. Im way below that. Going to take a video of the fuel pressure to see what it's doing.

Depends on whether your tuner uses the vacuum line or not. Most of the tuners like to set base pressure as 43-45 and to use the vacuum line. There are three kinds of pressure - regulator pressure (set with the adjuster screw), manifold pressure (for those of the vacuum line hooked up), and pressure at the injectors. Mine was set as 52 for the idle fuel pressure. With the fuel return, duty cycle, and recorded pressures under WOT, one can actually confirm if the fuel pump is capable of supporting the power under WOT, based on the fuel your using.

So recently my car has been feeling a bit sluggish and i noticed that my max boost readings were only about 4.5 lbs (down from about 7.7 right after system install). So I either was experiencing belt slip, had a boost leak or my filter was clogged. I really didn't want to remove the blower, so I cut the filter in half around it's circumference & pulled it out. Wow, super clogged, as you can see below (after only about 6 months of use). I then built a "turbo-guard" type of inlet screen out of 5/64" opening stainless (very strong) screen that I sourced from Summit. Now, i'm not sure how long I'm going to run w/ this setup b/c although it will certainly stop the large stuff from getting in, lots of smaller dirt will flow right through. But wow, what an improvement. I went for a quick test drive & was seeing between 9.5 & 10lbs of boost during 2nd gear pulls. Needless to say, the car feels waaay stronger.

I like how you just cut the K&N filter! Haha. That's something I'd probably do next time if I know I'm going to replace it with something else that does not require me to take out the blower.

What's your pulley setup?

I'm experiencing really low boost myself (7 PSI average) and that's with serpentine belt slip & a really clogged up K&N air filter + busted up at that to make things worse (it looks almost like a cup).

Without an air filter you should be running close to 11 - 13 PSI depending on what your pulley set up is.

If you're only pulling in 9.5 - 10psi then there is still something wrong with the boost you have (because I have similar problems, just may not be exact same as you).

I have the "stock" pulley setup that comes w Aaron's full kit, which I believe is the 8# setup.
