4cyl tach to 6cyl tach

Now im not sure if there is a difference but im 99.99% sure. Because now that my motor is broken in I was getting on it like a raped ape and was maxing out at 4.3k. Now I know a stocker can pull to 5.4k with emissions on it. So if someone can give me a possivitve YES then ill go look for one.

If someone one here has a turbo cluster or just a 4cyl cluster they want to sell or trade for mine, shout.
