Hi all,

I'm new to the forum and the Lexus world. I just bought a 2003 IS300 5sp. and was wondering if anyone else is experiencing my problem. I find the rpms hanging during shifts i.e. they don't drop down as fast as my past cars. I'm having a hard time driving the car smoothly and matching the rpms on down shifts are nearly impossible.

Also I heard you should be driving your car like you stole it because the ECu has to "learn" your drving habits. Should I be driving a brand new car like that? Isn't there a break in period?
