I can give advice but i wouldnt say im the best to ask for the V6, but i do have a bit of knowledge on it, fuel upgrades required etc. Anthony knows a fair bit, as does Andrew, Dave and Adam from the states, ask Andrew for his details. As far as it goes, best bang for your buck and most support is available for the TRD charger. I don't know if you went for a ride with Anthony, but that thing is literally mental.
