New Problem

[OklabyGodhoma]

I recently did a full DOD release using a kit from Texas Speed. New cam, new VLOM plate everything new. Had the computer flashed by the guy that CPR recommended. A week after the car starts throwing a P0420 code. Tried using Berryman’s as well as a gallon of Lacquer Thinner with 10 gal of fuel. Still throwing the code. Almost forgot also new exhaust manifold gaskets.

Looking for ideas or if anyone faced this problem after a DOD release. I’ve got almost $4K in this engine now and it’s pissing me off…..HELP!!!
