Narrative:

After exiting runway 30L onto juliet we were given a clearance to taxi to the FBO via victor. I was approaching the taxiway victor signage and turned left before I reached the sign. It turns out that I turned on what I believe is now taxiway whiskey which the nos chart shows as runway 11/29. This is now a new taxiway which parallels victor. The chart needs to be updated. The yellow line turns left onto whiskey. I was confused as I had apparently already passed the sign for whiskey when I was given the clearance and thought the first taxiway to the left would have been victor. I now realize that I should have passed the taxiway sign before turning. I have brought up the idea of painting the letter of each taxiway to our runway safety action team; but this was deemed too expensive and there is apparently a paint shortage. I believe this idea would have helped me in this case at sjc where there are two parallel taxiways.
