All vehicle manufacturers are forced to meet fuel efficiency standards by the government. Don't you realize that if there was an easy way to better the gas mileage, they would all ready be doing it! JMHO!!

Generally I'm very anti-performance chips.. There are assorted reasons for this but two of them are chats I've had.
One was with the national service manager for Workhorse Custom Chassis (he was dropping off a part to my house, Now that's first class customer service) and he was telling me of a highly modified engine (Not just chips but a bunch of other stuff as well) which had a piston that had gotten religion.. IT Was Hole-y (Pun inended) Of course the failure was caused by all the mods and running the engine way beyond spec.. So sorry Charlie.. No warranty
The second one was a Ford Rep.. the differences were: 1: Ford engine instead of Chevy 8.1 2: Car instead of Motor Home
The common factors: Nature of damage, Nature of Mods, and Nature of warranty (VOID)
That said: There is a post on this forum about the ULTRA POWER chip from Mike Brazel... This is the one chip that I am seriously considering. Of all the chips out there this one was developed JUST for motor homes and there is a slight chance it might actually pay for itself over the life of the coach.
The other approved mod is the Banks Power Pack.. However I seriously doubt if it will pay for itself.

WA8YXM, since you brought up a gasser, I think that is a whole different ball game compared to chipping a diesel. HOWEVER, I just went through the process of calibrating my gasser and have a much greater understanding of the implications. A generic chip may be able to fix some problems, but I really question the value, unless you first do a data assessment of your engine. Every engine runs just a little bit different. The weight of the coach will effect the mixture at WOT, so there is potential to fine tune the calibration to your specific coach and engine. I also believe that many (especially older) of the computer calibrations are set up for a pickup truck, so it is possible that the OEM calibration is leaner than it should be for WOT. I doubt fine tunning the mixture is a recipe for trouble as a the performance increase is comparatively small. Truthfully richening the mixture at WOT is probably a really good idea because it will make the engine run much cooler. I would guess if someone holed a piston, that the engine was lean and the calibration was not done to match the other mods. All the more reason to get test data before chipping it and have the chip customized to your engine. For OBD1 ECMs the additional cost is around 50 bucks - 50 bucks well spent.
