Nice work dude. It's a testament to you and your progress on the truck. The times 'look' bad but the Ram 50/Mighty Max was never meant to be more than a workshop hauler and it seems every outing yields improvements. If you haven't done an oil flush you have nothing to lose, and I'm still sure there's space for improvement experimenting with the ignition timing. Maybe some tires with grip just for the strip. Once you reach it's limits in stock mechanical form it'll be time to look at headers etc.
