I have my exhaust on, gauges on order. I see there are 2 different sct gauges people have mentioned, the x3 and xcalli. also what about getting a custom tune and from who? I'm not worried at all about making it fast or anything like that. i use it 95% of the time for towing my race car around and want to get the best mileage/performance for that purpose. All the info is in my signature at the bottom about the truck. Thanks for any info you have on this
