Tach jumps all over the place! MSD 6A box, stock in dash tach....
I recently did a Th350 and 3,200 stall converter swap in my firebird, and now my car revs up a lot quicker, and I have this problem......as soon as I floor it, the tach starts to bounce all over the place. Whats the deal?? Its the factory in dash tach hooked up to an MSD 6A box. any ideas?? i need to fix this, I'm running the car the 19th on nitrous and a tach would be a nice thing to have.
