I have a big 5" tach sitting in front of my face and never look at it... I do have a shift light and thats what I go by... on the Rampage I put a small 2" tach down on the counsel that has a shift light in it and I can see the flash of the shift light but cant read the numbers while running... I was planning on taking the tach out of the race car and use it for set up only.. seems like a waste to even have a tach in it
