I bought a 89 SC around the begining of this year. Everything seemed fine, supercharger sung, car felt powerfull, only a few electric problems. One day someone started revvin on me at a stop light, so when the light turned green I went to take off, but my car seemed like a regular Thunderbird not an SC. I took it to my buddy's auto repair shop, the cars not throwing any codes, supercharger still sings, boost gauge still shows boost, the bypass is not stuck, clutch dosen't feel slippy, and I asked around if it could be my tranny. People tell me, "no, can't be the tranny. it's a stick". The car just seems lame. If anyone thinks they know what it is PLEASE HELP. Any info. would be great.
