here soon after i get some new gears dropped in .. i'm going to try to get a few extra ponies/also fix the speedo .. but where i work i can get a new hypertech at our cost which is nice and about 220 bucks shipped to my door my questions are ... 1. Is anybody running a hypertech on their late model 4.0 , 2. Did you notice much power increase , and 3. Any improvements on MPG ?
