well, i had the blower rebuilt and a 10% put on. I was scared of blowing HG's, but since i cant drive till august (seizure), I did it, then got the exhaust done later. before the exhaust, i got on it without flooring it, and the boost went between 10 and 15. Once the exhaust was done, I would say it gets 12 right at 5000 RPM. I dont get a check engine light, and I cant tell any boost leaks. I used Mapp Gas (out of propane) to check for leaks on the parts I took off. no change. It feels slower than it was. I measured the pullys circumfrence with teflon tape (I know, it stretches.. I was careful). the stock one came to 3.0245 diameter(close) and the 10% came to 2.8653. so it is a 10 %. I dont know what to do. My auto tranny is FRIED. no OD and when locked into 2nd, it slips below the rpm it wants to be at, but give it gas and it pulls hard from where it wants to be at. (example.... 2nd gear wants to cruise at 3000 RPM. locked into 2nd, it will drop rmp like neutral until you give it gas and it jumps to 3000, and pulls hard from there). could this or a torque converter cause problems?
