[QUOTE="BravoZulu81, post: 1529693, member: 23652"] I’m pretty well a granny and rarely get above 70mph as I notice it drop then too. Granted with my 37’s I don’t expect anything like what you are getting but I’ve always had them and just feels different I guess. What tune do you run? I may reload mine to see if that helps too. I’ve also tried a few different additives to see if they help. Usually it seems like they do for the first 1/4 tank then falls off again. Sent from my iPhone using Tapatalk [/QUOTE]
