I made some test runs today with KR and vacuum/boost gauges digital and large on the S4 screen.
About a dozen WOT runs, from slow soeeds like an entrance ramp to a starting 65 for the Mustang that santed to run on the parkway.
Most of the time KR was 0, but most readings i got were from 0.5 to 1.5. I had a random 2.5 and saw a 4 only once but i had the pedal literally on the floor.
I dont like to beat on the car after all it is 13 years old. Every time I felt like I was getting into it to go fast (not quite WOT) the KR reading was at 0.
One run i was at 4599 rpm, boost at 8.x lbs and KR was at 0.8. Next I need to do some data logging so i can drive without looking at the phone lol. No trees were harmed while taking these readings.
Struts are fantastic though , definitely needed them and it makes a huge difference in the ride and handling.
