No/Little boost pressure

[scottmcd]

Just got my Banks SixGun W/ speedlaoder installed, with 4" ss exhaust, & K/N filter. Ran Dyno 2nite & got lower #'s than Stock, was not getting any boost. Could this be a stuck wastegate??? Any help would be great.

Sounds silly, but be sure all your intercooler boots are firmly attached.
