Off load and cruising that sounds about right Ron. You still want it reasoanbly economical. Whats the readings full boost on a long pull?

Reads 11.8 on full throttle in 4th at 6k rpm pulls really well with this new turbo :-)

I checked my carb when I first got the car and the only jet that's different is the main it's 1.3mm everything else is standard
