^ Yup, I agree. The modded stockers I have seen all over the place, but still within ~40cc of each other. I don't think you can mod the 06/07, and you shouldn't. By the time you pay for the older ones, mod them, then get them flow tested/cleaned, etc. you could have bought brand new injectors.
My whole point was, the OP could upgrade to a VF series and be ok. Obviously if he wanted to take the VF to it's max potential, then fuel is always a good upgrade.
AND Well if he doesn't have EM then none of that matters...
