Hey JayG; Good to have an instructor chime in! I hope I'm not giving bad info. Some of my style may be due to my driving a 2.5 so keeping it in the power band (3.2k+) is a job. When on the freeway I typically don't use 5th until above 75 indicated where I can keep in the aforementioned power band. That said in response to the OPs question regarding poor fuel mileage my thought is he is shifting just as he is entering the power band but more importantly may be spending too much time below the power band and in the lugging range of the engine with the knock sensor picking up the gears/chains lashing, then retarding ignition timing causing the poor fuel economy? If he is shifting 3.2 k then he is 2.2k after shift. OP lives in Monterey so as I'm sure you know it is not all sea level driving there. Viva Laguna Seca!:dance:
