Thanks for the info, I was thinking there may be as problem with air flow and MAF sensor. I still want to try it though.The ‘05-‘06 GTO had a scooped hood that wasn’t functional, but a company made ductwork to fix that. If I recall correctly, though, it really wasn’t worth it. It made for some really tight turns in the air duct, didn’t add any power and in some cases caused trouble codes due to the short run and tight turns. Something about the MAF too close to the outside.
