After years without a mustang I am picking up a 1995 red Gt Convertible. Here are the details. The engine has the stock bottom end with 80,000 miles, Trick flow 350Hp combo(heads,intake,cam,roller rockers, etc), Paxton Novi 2000 supercharger, 30lb injectors, MSD distributor, new Tremec 5-speed with centerforce clutch, fresh 8.8 rear with either 3:73 or 4:10 with a girdle. I am trading my Z28 for the mustang. Being an auto tech I have checked the mustang from top to bottom and it is in very good shape. I have 2 issues I need your advice on. The car Is not running quite right. I believe that all these parts were bolted on with out a proper tune. I am a little new to this. The motor surges at idle and is runing very rich. I plan on adding an AEM wide band a/f gauge. Should I take this to a dyno shop and have them tune this or is there a way I can do this myself. My second question is properly tuned how much HP shold the car be making. THe Z28 I am trading for the car is in the 10.90's. I would like to be rinning mid 11's with the mustang is that possible? Also I notice thay don't offer intercoolers for the 5.0 only the 4.6's is there a reason for that? I am also already planning a 347 stroker. THanks
