so you are saying that before you bought your first turbo that you knew everything about this car. I bought it for cheap because i want a turbo. It just seems simple to fix with the ISC or TPS. But i dont know about all these data loggers and crap. The oil, fuel filter plugs and wires has all been replaced. I know that i need to do the work myself but its a way different concept then the 420A. Thats pretty shitty that you cut me down for NOT knowing about this. Granted it needs work when i boutght it but still I think you can not have an attitude with me about it. I just want to meet someone from this area that is familiar with the 4g63.
