Thread: Will rocker arms require a retune?

My car already holds 1st gear to right around 5900 RPM anyways so how beneficial would that be to me? 2nd shift however only goes to 5500 before shifting to 3rd. But I can always hold it in 2nd for just a little bit longer. Thats what I did at the dragstrip so it would hold 2nd gear through the traps.

just because its up there doesnt mean its making any decent power. rockers will allow more air in so you will be making better power the higher the RPM's.
