early 99 16 max boost

[early99smoker]

I have a 99 psd with 100k miles, I have a ts chip, s&b intake, and four inch exhaust, and the edge insight. At wot I hit 16 psi, but no more, I it feels like it runs strong, what do I do to get more boost? Sorry i'm new to this

You might have leaks somewhere, exhaust or intake side.
Pressurize intake side.
Check for leaks on exhaust side with black soot marks or leaking/bad EBP and sensor or bad MAP possibly.

I'm nit seeing any soot, everything looks pretty clean,

Sorry for sounding like an idiot, but i'm just learning this stuff, but what exactly does boost do?

[jesilvas]

If you're using the Edge that reads directly off of the MAP sensor, then either it's correct, the MAP sensor tube is leaking, or the MAP is wrong.

If you're using generic TS tunes, than your boost might be a little low for what it should be, but idk.

How would I know how to test the map sensor

unplug it while it is running, if there is a noticeable difference it is at least working. also check the vacuum line to the map for cracks, if it is an early 99 you will want to look at replacing the vacuum lines. I have an e'99 and I put a boost fooler on it to find that the vacuum line was completely rotten,

[jesilvas]

It's a boost line, but same idea.
Also, unplugging while running, you won't tell a thing. That's for a bad ICP sensor.
You can pressurize the intake system to a known PSI on a mech gauge, then check it against the reading from the MAP on your Edge.

Thanks guys I'll check it out, just got done pulling a 13k trailer and boost was staying at 16

I can't find anything, even unplugging the red line to the wastegate it stayed exactly the same
