Does anyone else have a response issue with the gas pedal on the 2008 ISF in auto mode with sport mode active? When driving, if I gun it, it's like the car has to think for a second before it goes...what's up with that? Maybe the computer learned wrong from the first owner? Unplug battery and reteach?

I was spoiled by driving my friends new C63 AMG, the car responds immediately.

My 2009 IS F have the same moment but from low speed. If i have 140km/h+ beast responds immediatly. If i have less than 100km/h IS F think one second before start.
In my opinion car is build this way...

I had a company called JMO do a performance rebuild of my Honda Prelude torque converter in the day...was expensive but improved performance dramatically...wonder if something similar could be done for the IS-F...

actually it's cheaper to slap it into manual mode for some hot rodding...was just curious if this was a lexus issue and it sounds like it is!

It's the drive by wire technology. 1sec delay is normal for Lexus. Buy the blitz controller. That will solve your problem.
