The last couple of months, my car has felt absolutely flat. I've been running the rotofab 93 Cortex tune with premium gas (from several different and reputable sources). The torque down low AND the power up top seem to be about 15-20% reduced using my ass to measure. I understand that a dyno is the only true measure, but I've had the car for 4 years, and feel like a pretty good judge of my vehicle at this point.
The oil is fresh, I've cleaned the MAF, throttle body, and gave the intake filter a cleaning and recharge. The engine idles well and sounds good, but there is just no snap to it.
I'm about to make my normal commute of about 100 miles (80% highway) and am wondering what parameters I should log/record with my cortex that might be helpful. Are there trims I should record prior to setting out and then do another battery reset?
Edit, for reference, my mileage has been averaging 19.9 with 80% highway @70. It was about 17.5 in the winter on the 87 tune prior to the cleanings and recharge etc.
Any help is, as always, greatly appreciated!
