How many miles have you driven since you first installed the VF540?
Correct, I had to take off the supercharger bracket just to remove the driver side coil cover to access the plugs. I debated whether I should leave that side off for future plug changes, but opted to re-install it. Perhaps I can just remove the supercharger next time. I'll have to look again how accessible the bolts are. For the most part, I only have a basic set of sockets and tools. I think the second time around I would be able to do it much quicker.
I had about 5500 miles on the 540 kit; installed since May. Never had a problem with check engines lights. I was running the original software the entire time. Nik sent me an update a couple months back, but I didn't bother installing it.
