Definitey getting used to driving the truck with the V8 in it now. And absolutely loving it. However, I'm curious, can someone tell me which fuel I'm supposed to be running a 1UZ on? 95 or 97/99? I'll be mapping it soon and playing around with the air fuel ratio and timing. So I'll be able to map it for which ever fuel I like. But I'm curious which fuel it was designed for and which fuel you all run on?
