My truck will not make more than 1-2 pounds of boost. I upgraded the turbo size and have went back and adjusted the tune. It cruises at a great AFR, idles, revs, etc, but when i try to do a pull, it will not spool. I can get it to 1-2 psi if I stay in it long enough. Here is a data log.

Thank you in advance.
And Tune. And list of mods/description of build.
Majority of the time its a plumbing issue.
But what size turbo do you have and what engine setup?
I see you only had it up to 3700rpms. Thats not high enough to build much boost if the setup is on the large turbo/small engine side.
we'll definitely need to know at least a compressor size, with an exhaust size on the turbo haha
Sometimes money isnt an issue, sometimes it is. Sometimes time is an issue, sometimes it isnt. Never at the same time are they both not an issue.

I ended up figuring this issue out pretty quick. Turned out I had a burnt plug wire, and it was making the truck very sluggish to get into RPMs. Not to mention that it is a 4.8 with an 80/88 turbo. I appreciate yours and everyone else's quick responses though. It means a lot.
