Not today, but a few days ago I switched back to my 93 tune. I have a 45 mile drive and I was growing tired of having to time my E30 fill ups. I've also been getting 32mpg vs 28mpg on E30. I don't really miss the surge of torque that was useless in the lower rpms. If I don't start modding the car, I may ask for a revision on my E30 tune to reduce the low down torque.
