hey guys, i just picked up a 06 evo and it has 18,500 miles on it... for some reason the gears seem a little short. I did some research and they said that on the 5speed trannies in 4th gear im supposed to be hitting around 117mph, but for some reason my car only hits 100 in 4th gear. i just ordered some new spark plugs, is it possible the cars not running full potential bc its running lean? if you have any other suggestions please fill me in! THANK YOU!

 

sorry for posting 3 times, my computer bugged out.
