Very impressive charts for stock turbo. Very smooth too considering. Are they adjusting VANOS now to remove that 4000rpm dip?
It is hard not to compare this to the race gas only ASR chart. You can see the ASR makes 20hp more peak, and holds that peak to redline. So there is much more power under the curve with the ASR kit. Then again how many people are really going to drop 8k installed on a turbo kit?
