baffling turbo..

[David Cooley]

Never seen red exhaust smoke, but my guess is the volume the pump supplies 
is dropping off... Monitor Fuel pressure at WOT during a run and it's 
probably falling off and running lean.
Red smoke may be rust from inside the exhaust etc burning loose and coming out.
