Remember trace detonation, headgaskets and bearings

[Shannen Durphey]

Anybody tuning a vehicle that tows, esp. pickups that pull heavy trailers, need to
be alert to the 60-70kpa tuning.  This can easily be a case of running there for
hours at a time.  And it's easy to forget to hook up the scantool, or think
everything's ok, and head out without even monitoring that area.

The guys trying to run numerically lower gears and low rpm power peak engines see
more of this type of stuff also.  Light cars, numerically high gears, strong engine
combination can be really forgiving. 

Bob V., are you down to 1:1 final drive ratio yet?
