Vacume Guage question

[farside847]

Got a new Tach and Vac kit and installed it over the weekend (thanks PICKMUP!)

Im sure it was set up correctely, but Fedex must have smacked it at some
point because the vac guage was pegged at 30 without any vaccume. With
vaccume it went further to the right. So I bent it back untill it made sence
to me. Now, at warm idle the guage says 18. It will go up to 25 coasting
downhill in gear, and drop to 8 going up hill. 0 when I floor it - Does this
sound right?

Also, my new tach workes great, but when I turn on my blinker the needle
jumps with every blink. Is this normal? Or did I do something stupid?

Thanks!
