Couple hundred miles on this tank and my little hiccup that I thought was due to low fuel issues turns out to be at the point where the thermostat opens and it rapidly cools the ECU temp sensor. You can watch it happen on the datalog. No big issue and at least now I know exactly what's happening and it's not problem. Runs a little rough for about 5 seconds and then it's gone.

On another note, I used to get 220-230 miles per tank and I'm already at 210 with over 3/8 of a tank left <img src="/forums/images/graemlins/smile.gif" alt="" /> Haven't even attempted to lean my cruise AFR's either. I think alot of it has to do with what used to require full throttle to pull hills (or a downshift even) is now just light throttle with no issues. Still not alot of horsepower on tap......but the torque is a huge improvement.
