My throttle feel of my SC is real slow. Under normal driving it feels sluggish, but if you punch it it will go. Is this normal or what? My Titan and other newer cars have much better feel. Is there anything i can do to improve it? Something simple b/c i'm broke!
your titan has gobs of low down torque and likely has a torque converter whose stall is north of 1900 rpms.
"Joe Lexus" is a 59 year old male. the electrontically controlled throttle and the a/t's torque converter and gearing are built to not snap necks off the line.
I would drive another SC400 first. But, I would bet that you will feel no difference. I would attribute what you have described to the conservatively designed off-the-line performance of the car.
When I got back into my SC after it was in the shop for a week after hitting Bambi on the highway, I missed the jacked up stall that was on my G6 rental car.
My suggestions...
Lextreme stall converter: $175 after the core exchange.
Lexus SC300 a/t differential: $150 shipped from Gazi.
