That is why I did it, so I can tune the VE.

On the contrary, "normal" driving for this vehicle includes 5500 rpm at 90kpa for 30 seconds at a
time, 400 rpm at 90kpa, and anywhere in between.  Unless I use the brakes or hook to a 10,000 lb
sled, I will not get a chance to tune for these conditions.

What do you mean by normal driving VE?  Normal cruising VE is 0-3500rpm, 45-55 kpa.  What about
normal heavy load VE?

I'm not doing a brake stand like smoking the tires, i'm driving 30 mph and holding the brakes to
load the engine.  If this is wrong, what do you suggest?
