if you can only see 10 psi max, then that means you have a boost leak somewhere. Untuned, these trucks will see up to 18psi, with custom tuning up to 30psi. I would start checking all your intake system boots for leaks, check your MAP line from the spyder to the MAP sensor, also look at up-pipes for signs of exhaust leakage.

Yeah, 10 psi is too low unless you are below 2000 rpm.
You won't be able to build much boost on stock tune until you hit 2500.

Have you checked to make sure your MAP line is connected? Did you have the issue before the OBA?

Not to hijack, but you're talking boost on a stock tune, so what should be be seeing say at 55% throttle position w/ 3000 rpm? Or 70% throttle, 2500 rpm?

You need to be under load to build boost.

Upload the pics to an album (created in your user profile). In the album, click on a pic and then below the pic are two lines of code- "Picture URL" and "BB Code." Cut and paste the BB code one into a reply. Viola! Pic in your post.

That is an over boost annihilator of the home brew type. It is used to limit the map sensor from seeing more that 22ish psi of boost. That is when the PCM commands the truck to defuel.
