Thanks for the thread. I expect to pick up my new WRX in about 6 weeks. I think I can manage the under 4K for the 1st 1K. My question is about what constitutes keeping the RPM constant for "long periods" of time. I have to pick up the car about 3 hours away from home. Do I need to stop or slow down at times to avoid the long periods - and how long is long? 30 minutes? 15 minutes? 60? Any thoughts?
