Hello, was wondering if anybody could tell me how to get more power from my van (99 Ford E350 Superduty cut-away Van)? I use it for pulling a camper (only in the summer) and I find it underpowered, with high winds, passing vechicles and hills. I have put on some parts to help (exhaust, chip, propane, water/meth, fuel regulator kit). All the stuff works great but seems still underpowered compared to my friend's 99 ford diesel truck. I would love to find a company that sells an intercooler kit.
Plus I was also wondering about the turbo and the injectors (heard that they could be upgraded) if anyone has heard or knows something about this and could pass on some advice that would be great> Thank you for your time.
