Thread: 200tdi timing

Hi guys im about to replace timing belt in my defender 200 tdi. Anybody recommend tweaking the timing for any performance gain? Also has anybody adjusted plunger with dti in bosche pump to 1.6mm?? Looking for anybody who has done any of these two mods and was it worth it. Cheers in advance

Those mods are the same thing.
I've had mixed results with advancing the pump on 300 tdi's.
