Well i just finished swapping out my stock DX cluster out with a EX cluster. Anyways it was simple.. plug in plug out. I bought my civic dx off some rice boy who had a huge monster tach. Anyways its not my style, im shooting for more of a sleeper look. But the thing is that when I drove with the Monster Tach I would NEVER and i mean N-E-V-E-R reach 6 grand. It was out of the question i would just loose power it wasnt worth it. But today after i did the swap i took the car out for a spin to see how it would do. And i found that the stock tach was reaching 6 - 6,500 before i would lose power and end up shifting, and I wasnt driving it any harder than normal. so im just curious if any of you have ever heard of this. and if you have any idea on which one is more accurage the Huge monster beast or the stock EX tach.
