Has anyone used Wynns EGR 3 cleaning kit, consists of 2 parts an aerosol sprayed into the air intake (after the turbo and intercooler) and a agent put into the fuel to clean and lubricate things like the fuel pump.

not really interested in the fuel additive but results from the intake spray look promising
