just a question for anyone out there with suggestions. i have a 99 35th ann. mustang. i put on a procharger stage 2 kit along with full exhaust and whatnot. i recently had my car dyno tuned by larocca with a pretty conservative and safe tune. as i was pulling my car into the garage a little while ago i heard a tapping coming from the drivers side head. it increased with rpms. it runs just fine but you can hear that tapping as you drive. i pretty much immediately took it to the dealer to see what was up. they called back the other day and said its blown...5100 bucks. now can someone tell me whats up here.. i dont think there is any need to replace the whole motor. theres just a tapping from the driver side head. could someone please help me out here, maybe give me an idea of what could be going on. i would really appreciate it. maybe point me in a few directions of what i could do or where i could go. if it helps the numbers on the car were 385 rwhp and 405 ft lbs. any help would be awesome, thanks!!
