Thanks for your help. I am currently running stage 1 93 octane. The car has no mods as of right now, but what i was saying was I'm not sure if the previous owners had done anything to it internally before selling it; someone had to of been in there because the restrictor pill was in the wrong hose, unless that's the dealerships way of keeping boost down while people test drive it.
So, I did the wide open throttle run in 3rd gear up to 6300, as usual around 4500 it started bucking, almost like it was getting deprived of fuel. Right when i reached 6300, a treacherous grinding sound came from the front end, so i quickly threw it into neutral. I also smelled what smelt like metal on metal only for a second, so i put it into 5th and it ran fine all the way home.
Cruising home in 5th
Your help is much appreciated.
