VW VR6, injector trim needed for port length differences?

Post by eMTea »

Hi!

Does anyone have experience with the VR6 (in my case a 2.8 24v), and know if the tune needs injector trimming og timing difference due to the different lengths of the intake ports?

Best way to check is a wide band in each runner or egt sensors,
If you did this you'd probably find that 3 need trimming to drop inline but obviously there could be differences between them all.
