newby, got a Patrol 2004 zd30di. I'm wanting to know what is the best way to tune my car and get the best performance. Can the ECU be flashed or do I need to get a Unichip I've fitted a 3" exhaust, guages, Dawes and needle Valve, next looking at a high flow filter box and pipework, and increase the intercooler and pipe sizes. Any suggestions
