As for me, I don't track my car ..... plus I don't feel the need to shift real fast in the higher gears, so as the rpm don't drop down below 4.500 before I give er the gas in the next gear.
Hell, I just want to enjoy my car ..... if it blows apart due to some mechanical defect ..... I'll just get another car .... I'm not married to this sucker......
