Torsion and Injection Quantity

Hello,

I recently replaced the timing belt of my 2009 Superb PD140 engine  (using the proper lockup tools) along with oil, oil filter, fuel filter, air filter and have been fiddling around with the torsion value a bit.

With the old belt the idle fuel consumption was around 0,6-0,9 l/h when the engine was warm. During acceleration there was this sort of a kick in the back at around 2500rpm.

After the timing belt replacement I set torsion at 0, the idle consumption and overall consumption was higher than before. The idle consumption was around 1,1-1,3 l/h. The power curve seemed a bit more linear with more pull at 3000-4000 rpm.

I checked the injection quantity and it was around 10 mg/str. With adjusting the torsion I managed to get it down to 5,5-6 mg/str and idle consumption around 0,7-1,0 l/h. The torsion value is at -5,4 and the power seems to be more linear but also a bit down. And torsion value of -5,4 seems a bit extreme.

My question is: in what range should the injection quantity actually be with a properly adjusted torsion value?

Best regards
