I am just curious as to whether anyone has tried this and if it even works.

Our only upgrade option for the MK3 is the 550cc injectors chip.

Would it be possible to run the 680cc chip made for the MK4.

If not, I guess it would be safe to say the Mk3 VPC is limited to 500rwhp due to the injectors.

Whats everyone thoughts about using the mk4 680cc chip?

MKiv chip wont work. Run 550 chip with an afc.. Anything over 550 injectors though I'd consider getting a standalone.

I know I've heard of a 680cc chip for the MKIII, they're just extremely hard to come by. People have ran 550cc injectors on the 440 chip with a GCC or SAFC with no problems. I would think that with proper tuning, the same can be done with 680cc injectors and the 550 VPC chip. However, I have no idea just how big one can go with the lesser chips.
