Message: [QUOTE="Trevor008, post: 1002605, member: 15498"] What rpm is "safe" or "optimal" to consistently run at on the highway? I am going to run 37's and want to get back the low end grunt and then some as compared to 3.55's and the stock 34's. I don't want to over rev at my normal highway speeds(65-75) but most of my driving is city or traffic anyways. I'd be willing to slow it down a little on my lucky few open highway drives I believe which makes 4.30's the optimal solution for me [/QUOTE]
