My svt is running like crap lately, i noticed pinging (like from bad gas)but i use high octane, and with the power loss, theres no boost at 3-4k rpm.. Not sure if theres secondary(butterfly) a clog, throttle body sticking, or what.. please help asap with any ideas...
You didn't say how many miles you have but from the symptoms, I would say your Cat is clogged.
