You posted what appears to be a quote that I posted. I didn't post that. It looks like you got your reply mixed up with my posted questions. But I think I see what your reply is..
You couldn't tell the difference between the LCE 4-in-1 and the Doug Thorley, right? And... your experience may be my experience. I could test each one and NOT feel any difference... but I sure would like to test them on an engine dyno.
Speaking of experiences... obviously each of us has a different level of awareness, experience and driving style. I have driven trucks that the owner thinks is a real modified cats-a$$ machine. But, compared to my more stock 22R, my truck would kick his truck's butt. I have also had a guy ride in my '85 and when I tac'd it to 5,000 RPM in 1st, 2nd, and 3rd gears, the guy says I'm going to blow up my engine!
...and says he never tacs his engine over 4,000 RPM!!
