I'm new to the site just joined but i have a question. I bought a new 2014 XRS I got 30 MTC on it with the muzzy full exhaust and the muzzy programmer. the problem i'm having is that it only runs about 55mph and tachs out at 8100rpm. took to the dealership they said it wasnt programmed for 30's so they changed it also three fly weights were sticking so they filed 3thousands off each which now they all open. they measured everything and said that its all in specs. they said they drove it today and it hit 60mph but it was going faster because it had 30's on it that the speedometer is off. but you just said that you set the computer for 30s so the speedo shouldnt be off. has anyone had this type of problem or heard of this im wondering if mine has an issue with the clutch or is it the programmer that the dealership put on it. please help:crying:
