Boost Numbers

Put all my gauges in today ran my truck down the road and my boost stayed at around 4-6 psi then on accelleration it would go to about 12 psi. I checked for kinks, none then I checked for Leaks best I could, didn't feel any as I was feeling around the turbo and exhaust connections after I first started it up. Don't know what to check now. Also while in neutral with trucking running I reved it up to 2500 rpm's and the gauge barely moved, I mean maybe 2 lbs. Does it have to be under a load and are these typical boost numbers? Thanks

going down road with cruise 4-6psi is norm, slight to mod acceleration 12 psi is about right. Engine does need some load to build much boost, Do you have a chip? that will make a difference also.

Agreed^ without a load its not gonna make much if any boost. Without a chip at WOT you should be able to get in the 18-22ish range if not a little more depending on the load on the engine.

I have the DIY intake a TS chip and 4" turbo back exhaust. So I'm guessing I should be seeing higher boost pressures with those mods?

I see ~25psi on my 80 HP tunes and 30psi on my 100 or higher tunes. You may have a leak on the intercooler boots or the up pipe gaskets.

If the truck has stock programming then that is about right. I see about 28 psi at WOT in any of my economy tunes. The engine builds little to no boost in neutral.

So I should replace the rubber lots on the up pipes? I'm assuming those r the 2 pipes on each side of the turbo that r hard to get to?
