Hi and welcome to mightyram! Whoever is driving the truck is having waaay too much fun lol. Seeing the stock 2.6 and 5 speed truck taking flying lessons says a lot about what the beasts are capable of. If you're going to keep it as an off road plaything, get rid of the Mikuni carb and use a Weber 32/36 kit. They're far more forgiving to work on and produce some well needed extra horsepower. Add some headers, 2.25" exhaust and port the head and you'll be grinning every time you climb into it
