Launch Delay I got a 97' Z28 A4 with a CAI. Everything else is stock. Had her tuned maybe 8k miles ago. I hadn't noticed it at first, but now I'm sure its got a delay when I hit the gas pedal. I'll floor it and it will just sit for maybe 3 or 4 seconds. It WILL take off, I was able to keep up with a GTO off the line this morning (I hope he didn't know how to shift or something). But yeah, this lag is killing me, any ideas... is it normal?

It happens like this...
Car is driving like normal ~2000 rpm, 190 degrees F, everything looks good.
goat tosses me a rev
i push the pedal to the ground, rpm goes down to like 1800 rpm
sits at 1500-2000 rpm for maybe 2 or 3 secs <---- ????
car shifts, needle hits almost 6k rpm, keeps up with goat
Its like I hit the gas and the car thinks about it for a couple of seconds. Nothing happens right away.

Sounds like normal A4 downshift delay. I always account for that when I was street racing my LS1 auto from a roll. Also the reason I bought another M6 this time around.
From a dig Autos rock. When your moving its kinda hope for the best or really know what mph your car likes to fully downshift at, but then that delay your talking about happens and the other car already has a head start.

hell, when im rolling at about 30-40 and i floor it...you better get ready to catch your head. I have a stock 4l60e..but i do have a tune, so that could be the difference
so you never been cruising the HWY and some car pulls up and hits it, then you do and end up in that dead zone where the cars just pulls in the same gear or down shifts hesitates then takes off???? Its normal for an auto.
