Always nice to get another opinion! I had a browse over at the audi. Net Forum and a few guys over there had issues with the valves, apparently there is a solenoid you can get that is either open or closed depending on settings, which theoretically should remove the risk of filling the block or the intercooler as others had seen...I also wanted to do this. But got talked out of it by the garage. They basically said they'd seen some of the kits get stuck open and fill the combustion chamber with meth instead of fuel. You can imagine what happens when you light that! If it's a track car aiming for more power. I'd vote yes. A daily driver you rely on I'd vote no. Plus, if Revo thought it was worthwhile, it'd be on the upgrade list. I'm happy with the aftermarket intercooler for helping keep temps down.
