Looks like there's a possibility I'll be getting a different truck later this year. I was wondering if anyone could recommend some good resources for performance parts for a 92 F-350 4WD. It already has headers and a catback system plus a 3" lift and bigger tires with Rancho 9000's. My biggest question was about the performance module you can get for it. Worth the money or no? I thought about putting a new throttle body or MAF conversion kit on it with new injectors, but I'm not familiar enough yet with the Multi-port system to know what to get. Also, is there any way to soften the ride a bit without sacrificing payload capacity. It already has rear air bags but are there newer better bags available these days? It would be used to carry an 11' Lance camper and tow a boat. It handles that job fine for the current owner but he says the ride is pretty stiff when empty. Any advice/ideas are welcome.
