The most expensive engine rebuild shops never road test, but bench test,
this includes, dragsters, Indys, etc. etc., never heard of road testing
for carb max. adjustment, the very best dynos are just spun by the wheels
sitting on the rollers. With the car going 80 MPH you only have about 150
lbs. on the ground , anyway thats how rebuilders do it, not going down
the road with a C/O tester sitting on the front seat, I've done running
adjustments on the timing. This of course is just my observations.
