I know to use the vpc on an na mkiv you need the chip for an mk3, but the largest injector size offered in mk3 chips is 550cc. Would i be limited to 550cc injectors or is there some other way to use larger injectors?

You can go with larger injectors. What size are you looking at? You can probably control up to 680 safely, even more.

To run 680's would i still use the 550cc chip?

i was hoping to go with the largest possible injectors. But i don't want any control issues.

I ran 680's with the vpc but i would recommend getting a FPR i would have a nice rich bog if i romped on the throttle. Otherwise it was alright. If your intrested im looking to sell mines as im going 1000cc. Only have one dyno run on them and about 200 miles or less. Percison, They fit the NA rail. GL
