DO YOU THINK THE BEST WAY TO FIND OUT WHICH MOTOR I HAVE IS CALLING CUMMIINS, OR THE SPARTAN FACTORY?

From what I understand all American Coaches built as 1998 model year will have the mechanical C8.3 engine.
You can always call American Coach with your FIN number and they will tell you exactly what is in the engine bay.
Ditto for Spartan with the VIN number.
Both American Coach and Spartan are very helpful and supportive of their owners.

THAT IS WHAT I HAD FIGURED I CALLED CUMMINS AND GAVE THEM THE ENGINE ID, AND HE SAID HE WOULD CALL ME BACK OR EMAIL ME. I BELIEVE THAT I HAVE THE C 8.3. WHICH MAY BE A BLESSING I HAVE HEARD GOOD THINGS ABOUT THE MAINT, AND PERFORMANCE. DOES ANYBODY THINK THAT $600-$1000 MAKES SENSE ON BANKS PYOMETER AND BOOST GUAGE, OR $1500-$2000 FOR THE BANKS PERFORMANCE UPGRADE IS MONEY WELL SPENT OR THROWN AWAY?

If your engine is the 8.3L computerized engine, it will be labeled ISC 8.3L.
The C8.3L was mechanical. The engine info is on a label pasted to the edge of the timing gear cover viewed from the passenger side on my C8.3L and just behind the main engine oil fill pipe.

You might also check in on the American Coach yahoo site. Lots of knowledge about your specific coach there.

OK here is my not so humble opinion. I have a C8.3 cummins. Its a great engine. As for adding something else for you to have to monitor and WORRY about, I say PASS. My engine gauges consist of a water temp, oil pressure, air pressure, fuel tank level, battery voltage, engine tach, and speedometer. That is all I need to know if my engine is working properly. I read alot of post where people are saying that the silverleaf is not working properly. Some will call it progress, I call it getting away from the K.I.S.S method. "Keep It Simple Stupid". Remember the more complicated the plumbing, the easier it is to stop up the drain!

I have a 97 Imperial with a 325hp 8.3L C mechanical engine. The previous owner installed the Banks kit along with the pyrometer. I can't tell you how much it improved the drivability of the MH, but I do know that as soon as the engine spools up and builds up boost I can accelerate right along with the cars from a stopped start. I also like the pryometer especially when I am pulling a long hill.

When climbing a hill your diesel engine is gonna run a bit hotter and then cool off when you reach the top. I don't need a pyro to tell me that my exhaust temp is going up . As for having power to keep up with cars, I'm not in a race nor should you be. Its a MH not a race car. My rig tips the scales at close to 30k lbs. Why would I want to subject my engine and tranny to jack rabbit starts to be able to keep up with cars.

It doesn't hurt it in the least as your engine is designed to run in a particular torque band and by taking the time to get it there you are lugging the engine more. Listen to a tractor trailer when he accelerates, he is working to keep the engine in it's sweet spot for maximum torgue. As for the pyrometer, I watch it so that I know if the exhaust is getting too hot I can downshift or back off before doing any damage to the motor.
