Torsion value 1.9 tdi pde

Hello to all guys... so for those who have already heard of the torsion value ( sincronizazzione between the crankshaft and camshaft of our tdi viewable with the vag )tell you my experience on my golf 5 1.9 tdi 105cv mot.BXE

Purchased the car in the 57,000 km, and found that the timing belt and all the rest ? still the original and I checked the torsion value was down by 3.4 then, and the value which come from the factory, I decide through the various information on the internet and move it to 0.5 because they say that it is the ideal... the Fact this well-known that with this setup the car reacts better and much more coppiosa, as it pleases me, and hold this value until now that I 82.000 km. at this point today I decided after various thoughts back to the original value to -3.4 given that I think that if the proggettisti have that value there is a reason no? you have done this try the car, but I immediately notice that ? less coppiosa you have a low to medium but more fluid to the high..said that they are on tilt because I don't know what value to give it to you that the engine is always regular!! I ask anyone who has experience give me some indizzio thanks to all
