The memcal that comes with the VT V6 Ecotec bolt on package, is that suited to all of the parts including the 69mm throttle body? or just the parts exempting the throttle body. I just want one that suits all the gear going onto it.

The memcal that we would supply in the Ecotec bolt-on package, as shown the link below, would be calibrated to suit all of those mods as listed. In addition too these mods, we would also be able to calibrate the memcal (within reason), to take into account your existing mods.
