|   Not Ranked : 0 score  Also sorry for my late response. I've also been busy with college. I'm in the same boat as you, as I've just installed a bigger turbo, an S3. I wouldn't lower the KR less than the stock settings, I think it's better to lower the boost instead. I'm going to start out with 17.5 - 18psi spring pressure on the S3 as I saw it recommended in a thread. I think that less that less than 3KR shouldn't be concerning unless it's a very long and constant KR, but just a few little spikes is nothing as tough engine mounts and rough roads can trigger KR. I have a trunk mounted water-methanol injection kit injecting in the middle of the cold pipe between the TMIC and throttle body. + I have an upgraded TMIC(haven't installed yet) and I plan on getting near max the power the stock engine can handle. I upgraded the stock MAP sensor to 3Bar and seeing if I can run 23 - 26psi on the S3, but that depends how much torque I'll be making and I'm going to make sure the boost stays low (20psi) till it gets to 4,000 RPM and then to taper off at redline so the engine stays fine.
