Finaly gutted the cat and Holy Cow! What a difference. Problem is, the car seems to be hitting 20psi. I basically have all of the fuel system andelectrical upgrades, stock mechanics and a MAF Translator. What would cause this over boost? There was definately knock under full throttle and one back fire. Running 41-43 psi fuel pressure. I checked the hoses that goe to the wasgate and underside of the turbo and replaced which ones were old and broken looking. Any help or ideas? Thanks!
