Just did the 140mph speedo swap now I have a problem
Hey guys just did the swap, seemed pretty straight foward, but as I rolled out my driveway I noticed that the speedo wasnt really accurate, I thought maybe it wasnt accurate under 25mph, but as soon as I got on the freeway I could tel it was completely off, I know for a fact that 1500rpms in 5th means im going 60mph but the new speedo says im going 40mph, what could be the problem?
