Too much sound deadening under brake & throttle

[Lugnutt]

I installed the recommended 3 layers of sound deadening plus carpet on my truck floor and I noticed that my brake pedal is pretty close to the carpet when braking and I only have half throttle when I mash my foot down on the peddle. Have any of you boys experienced this problem? I'm wondering whether there is a way to adjust or bend brake or throttle linkage to raise them up a bit so they have more floor clearance or if I need to dig out some of insulation.

Sure would appreciate some advice on this.

Thanks
