I took my car to be dyno tuned this week. got there dropped the car off went and had lunch. everything going great untill I heard him say thats it. on I guess he got the base tune done but on the first hp pull it broke the belt inside my powerdyne :BangHead: It made 268.4 hp and 289.8 ft lbs with the belt broke inside. I geuss thats not bad for a stock bottom end and heads. the bad news is it trashed the supercharger. it has shaft play now and the bigger gear inside that the belt turns has damage to the teeth. this sucks!!!
