Leaks can be of any size. When fully pressurized to 20psi, I would lose 3psi... before I fixed the leaks.

Good news!! Found my leak. I was degreasing my engine valley, after hosing it out I went to start the truck and the engine hydro locked. Turned the motor over by hand to free it up. I figured the only way it could of hydro locked is the orange intake boots must be leaking. Found the clamp on the driver side boot cocked and half of of the boot. Replaced both boots (quick 1/2 hour job) now putting out 20 psi boost instantly and increases to 24psi. Thanks for all the help

So... did you notice a difference in the seat when the fun meter finally went to the right of center?
BTW, I was passing two vehicles today and noticed my boost reached 28 on the 60e tune.

More fuel + timing advance = more boost

There are boost limits set by the PCM and the wastegate actuator is like a "fuse" at 24-25 PSI. I'm not an expert on this, so I have to ask if fuel pressure is intentionally lowered in a stock tune - I wonder because the stock tune is so much quieter. The fuel timing and quantity will definitely get things happening, and it's the rapid acceleration that blows our hair back - for those who have hair. Another thing to remember is you don't want soot at the pipe. A puff is OK, but low-altitude skywriting is just a lot of wasted fuel.

I bet it looked something like this.............
I was only able to make 15 psi before I tuned it, then still 15 psi after. I fixed that when I did my Van turbo install and I can hit 27 psi at WOT in any of my tunes
