On my 2001 Winnebago, F-53, the plug for the computer hook-up is located inside, on the right side (toward passenger side) of the steering column, just up under the plastic trim.

Get a flashlight and a mirror and lay down next to the driver seat and look up into this area and look for the characteristic plug. It seems to be hidden well, but once you locate it you'll be good to go..............

Also, please let me know how the chip works, I'd like to get one if there IS a real benefit.

Let us know how you make out.

Yes that is where the OBDII plug is on mine also. I use 87 octane in my tank and regular dino 5w30 motor oil. I change oil every 3000 miles or 1 year, whichever comes first. I am not sure of how much more performance you expect to get out of a motor pulling a 20,000 pound vehicle. Keep us informed of your results.

There is a large discussion on the 5-Star Tune on the Ford Owners section here on the forum. I can vouch for it to improve the V10 shifting and over rev and a slight improvement in gas mileage. As for octane, ratings change based on altitude, so a higher octane at sea level is a lower value at 5,000 ft

I wouldn't waste my money on such an expensive oil. A synthetic blend (Valvoline or Castoil) will give you just as much protection for $2 to $2.50 a quart less in money. Octane ratings are a little overated. If you are going to be climbing up to above 5000', yes it has it's benefits in helping to produce power otherwise your just blowing money out the exhaust pipe. The one good thing is that most of the time 89 and 92 octane is not blended with alcohol and most 87 rated is. Especially in the midwest. Won't go into detail here but alcohol is not a good thing in fuel.

Royal Purple is no better or no worse than any other synthetic oil. RP makes some outrageous claims for efficiency and wear which are pretty much unproven except in RP's private testing.

For a normal RV that has limited mileage per year, the cost for synthetic is not worth it. You will wind up changing the oil on a time basis and not mileage anyway.

As suggest, several of the semi-synthetic or dino/synthetic blends would be much more cost effective.

Now running a full synthetic in the transmission and axle is a good thing to do.

Run the lowest octane you can as recommended by the engine manufacturer. Adding a chip to a gasoline engine results in minimal HP gains and very little increase in fuel economy. A chip also may require the use of a higher octane fuel to prevent the engine from pining. Most newer engines have a pre-detonation or ping sensor that willback off on the engine tuning to prevent pinging.

The octane of the fuel does not change with altitude. Its the octane requirements of a naturally aspirated engine that drop with altitude do to lower air density and thus lower dynamic compression ratio.
