Dead Pedal is back!

[dzl_x_4x4]

A couple of weeks ago I installed 4" dp and exhaust. since then it feels like I have dead pedal again (originally had it and the SCMT1705 took care of it). I originally thought it was turbo lag, but when I have it in park and start to press on the pedal, it seems to require more pedal to even idle up.
So, is that lag or dead pedal?
Anyone else have the dead pedal return?

Don't want to do the dead pedal mod, if that is not the problem.

Thanks

Able to pull any codes from it Brett? My first thought would be the APP (Accelerator Pedal Position Sensor) might be belly up?

I had P0000, P0238, P0475. I cleared them without restart, then had the P0238, P1000, cleared them w/o restart and had P0000, P1000. Then I stopped for now. Probably will return the program to stock and then some other setting.
I have the EBPV terminator and Dual Boost Press. Relief coming from blackclouddieselperformance, should be here any day.
