I currently do not use any FE instrumentation and I'm beating the (2008) EPA by 40%
if we're using the old numbers, I'm up 24%.

Either way, I think that the lack of instrumentation is really holding me back at this point. There are several techniques that I don't use now because I can't do them "correctly" without instrumentation.

For example, I don't P&G on the highway. My much lower Cd should really help me out in that area, and make P&G a very viable technique on the highway. But every time I try it, my next fillup sucks. I'm sure that there is a way for me to P&G on the highway and reap big gains, but I currently have no way of knowing about the finer points of my technique.
