Yup, $50 down the proverbial drain but what can you do. I recycle...run extended OCI where I can, and the DIY aspect saved me a few beans.
Both myself and the wife noticed something was off, so there was no inverse placebo on the car. I wasn't expecting it to be any better (as with some other applications where Redline felt better then stock), but having it go backwards...you notice that quickly.
