crisp part throttle for a day....then "dulls" out...
Just as the title says. After a few miles, part throttle doesn't feel as crisp. I flash it again, (while the motor is still hot) and it's crisp again for a bit, then just feels dull again. I've had this issue forever, just wanted to see if any of you experienced this. 02 sensors?

The tune is great WOT, but I've been chasing this "dull" feeling after a day or so" for a few years. Not sure if that's just fuel trims richining up? LTFTS are off.
