The only time my truck will make 15 psi of boost is when shifting into 3rd after launching it, or if i am cruising and mash it to the floor and it downshifts. My question is.....is this how it should be?

No, on a good working system you should see the same max boost level tru all the gears. You should probaby start seeing max boost around 3000 rpm depending on your setp and it should stay same tru the higher rpm.
Of course if you are crusing and punch it, you might see some boost spike but then after that it should level off.

Assuming this is a stock chip...

Are you judging this from the dash, or an external gauge?

The dash has been known to lie.

If an external gauge, you might need an extra turn or so tighter on the WG rod.

Could also be a sign that the fuel system isn't quite up to snuff. Without some scan data, it's tough to know for sure.

Track day in Sabin, MN, Oct 13th. There will be people there with scan tools...

Later,

I think my truck has a stock chip, how do i tell? I have an autometer boost gauge installed, i know the stock gauge is crap. I will try a turn on the WG rod first......

Pull the ECM. If it's really untouched stock, your ECM seal will be intact.

About the only way to know for sure is to look at the chip itself.
