I have a 2009 Four Seasons RV on a 2008 Sprinter 3500 chassis (rear dual wheels). What performance chips are available. What are recommendations on intake and exhaust modifications. What might be expected from these various item in increase in torque, increase in horsepower, impact on fuel economy? What vendors are suggested for these various items? Any ideas of costs? Note that the curb weight of my unit is about 12000 pounds. My name is rongardner, e-mail address is gardnerinsurance@comcast.net. Thank you Any comments on impact on dependability? I've never been on this site before. I hope the response can be to my e-mail with names of companys, e-mail addresses, phone numbers.

I looked around for quite some time for my '06 2.7L I5. I haven't done anything to it yet, but even with a brand new resonator it still feels wanting. It has a 10' reefer and insulated cargo box by the way. It does OK on the highway, but once you hit the hills the trans downshifts and it's all over. Reminds me of driving my old flatbed 12.7L MB Freightliner with a 45K load! Alright, it wasn't that bad as it can still pass loaded semi's with ease.

There are no chips. Best thing one can do is build a custom cold air intake. I have yet to get the parts, but I've ordered an Amsoil cone filter already, then I can build around the filter once it comes in. With any luck I'll get slightly better mileage. Total cost won't be over $100 Canadian. Otherwise, there's not much else you can do to increase performance. The exhaust is already 2.5" diam, at least that's the size on my I5 engine. I dare not go any bigger as I don't want to loose torque.
