Even a stick will be slugish if its not in the right gear and rpms.

Yea, but my problem is that I can literally floor it in 1st and 2nd and it doesn't pull hard at all. You can view my YouTube video in the Gas Pedal Delay thread. I recorded some clips showing how I can break loose my tires on a roll in 1st when "cool," record the speed the car revs up in 1st and 2nd, and then show it again when things are "hot." The video will show you that on a roll in 1st and 2nd, the car revs up slow as if throttle isn't even opening up. That's why I don't think SB will help my situation.

I'm perfectly fine with the throttle response of this car immediately once the car warms up after start up. Then after driving for awhile the throttle response becomes sluggish to the point I find myself trying to give it more gas to get it to go anywhere. It's bad when temps are hot out there.

Sorry for going OT in this thread, but just to make things clear about throttle delay versus not getting power when applying 50-80% throttle on a roll. I'm going for another test drive with the tech this afternoon since it's warmer.

[EDIT] Drats... had to reschedule. Hopefully it doesn't get any colder.

could what you are describing, (after things get hot) be heat loss? I dont know if that would affect throttle response or not but I do know it robs you of hp and the ECU changes settings to try and compensate.

I'm not sure. It's just everyday driving, and it doesn't involve hard driving. I drive home from work, and when I get close to home it feels like there's no power at times. Like if I accelerate in 2nd with moderate throttle and let it rev up past 4k, I can feel the engine holding back and not accelerating as hard. If I progressively press the pedal down to the floor it doesn't lunge forward and push me back to the seat.

It'll be nice for someone who has a similar experience can test to see if SB actually does anything after a long day of driving.
