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
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.
