Boost Troubleshooting - with numbers

OK - so I am doing some troubleshooting prior to getting any PHP or other tunes to make sure my *mostly* stock truck is working properly before I spend money on tunes.

So - I am down to finding out if my turbo is decent or not - I have a HYPERTECH programmer 3 on my truck - and even with that I was only seeing 17 lbs WOT.

I unplugged the red line to the waste-gate controller. With that off, I can get up to 21+ lbs of boost WOT (I had to back off as I ran out of road) - I assume it would go a bit higher.

Now, I know this is up for debate, but what are these numbers telling me? (Other than the HYPERTECH is a POS and I need to put it back to stock, spend some cash on some real tunes - and go from there)?

Is my waste gate controller bad? Something else?

Should my numbers be higher with the line disconnected? I don't see/feel any leaks, but I suppose there could be some. I was mostly checking waste gate control functions with this test - my issue is, I am not sure what the results are telling me.

Opinions? Thoughts?

Well 17lbs of boost is about what these trucks put out stock. The stock turbo maxes out at about 30lbs. Personally I don't recommend having your waste-gate unplugged but that's just me. I have never used a Hypertech myself but my TS chip with canned tunes pulled about 25psi on stock injectors. If you think your loosing boost, check your intake boots and up pipes.

Thanks for that info about what the truck produces stock - I have tried searching here for that, but some folks say it goes much higher than that which is why I was looking to see if I had an issue in the first place.

I am now confidant that I do *not* have an issue - and can now proceed to get to tings like tunes and other mods. Just needed to establish a baseline.

Thanks!

I have a mostly stock 01 with little mods like a 6637 and whatnot, and I can pull about 20 psi of boost with my Edge tuner. My exhaust manifolds, and up pipes leak profusly. Stock "OK" spec is 16 PSI. I would pressurize your intake system and check for leaks, other than that, you should be good to go!!!

Have fun!

i would check your up-pipes and make sure they aren't leaking that's a common problem.
look at the firewall and see if you see any soot, you can look from underneath too.

Thanks all - I don't think I am leaking, but I figure when I do the mods I am planning, I will probably swap out the hoses/connections anyway just to be sure.

In the meantime - time to crawl under and look for soot.

Thanks!
