Well finally got the truck dyno'd the other week, and am pretty happy with the results (i think, not sure why the torque goes up and down so much??). The calculted power at the flywheel was 189kw...so everything must be running right.
Click the link below for the report taken at the wheels with 33" tyres.

I got them to check the mixtures as the truck seems to still use more fuel than it should, which at best is 20l/100km around town....but gets better on the highway and down to 15l/100km.
The mixtures were perefect in the lower revs, but once over 4000 rpm they became very rich....does anyone know if this is normal?? The dyno guy though maybe the restrictive exhuast headers and intake?? Removing the airfilter improved it slightly, and made a gain of 13hp at the wheels....time for a K&N filter I think....
