boost leak maybe?

Well i have all the mods in my sig, and at first the truck seemed to have alot of power, bit it seems that it has slowly been declining, before i could break traction easy and now i cant. and now if i get on it enough that the tranny doesnt down shift and the boost goes up pretty high it doesnt put you back in your seat like it used too. Im thinking maybe boost leak? cause i can hit 28 psi but it feels the same as 13 psi. so whats the easiest way to check for a boost leak?

He means to reload the tunes on your PCM. If you have 28psi of boost, you don't likely have a boost leak., although you might still check.

I would start with reloading your tune and go from there. It could just be that your transmission has learned your "normal" driving style and that is why you can't break the tires loose. As a second consideration, you might use a diagnostic tool like AutoEnginuity and see how much torque converter slip you have to see if the power is getting to the driveline.
