I just had 4.30's installed in my 98. I installed the speedcal and now as soon as my speedo reaches 10mph it spikes to 40 and goes up from there as my speed increases. My car has also started going dead when I start to slow to a stop. I have checked and double checked everything and can't figure this out. I have even changed the dip switch settings just to see if that changed anything. What else can I troubleshoot and what in the world could be the problem?
