Is is a good idea to run an aftermarket tach and shift light when you have an a4? I know the factory tach isnt that accurate so is having a tach and shift light a good idea or is it more accurate to just let the transmission do the shifting on its own?

 

just let the trans shift on its own because you will never be as fast a accurate as the computer

 

Its automatic for a reason, if you wanted to shift manually should have gotten a manual. The tach might be fine to use, but I laugh at anyone who has a shift light in an A4.

 

Unless you have a full manual valve body in your car.. leave the shift light OUT.

 

ok thanks guys....i fully understand!

yeah for you, def. let the pcm do the shifting. for me, however I DO manually shift mine. cause its a 700r4 swap. and the shift points while it D or OD are too low rpm. plus on the older trannies manually shifting brings on full line press as opposed to what the TV cable THINKS the line press. should be.
