Funny, my 2.0t has an immediate throttle response but seems to fall flat on the top end.

I did notice a major drop when temp is high 90's and running A/C.

 

Thanks for the advice. I have tried sport mode, and it does eliminate a lot of the turbo lag, but then MPG becomes ridiculous. It's nearly impossible to drive in NYC in sport mode all the time. The car just jumps in sport instead of not going and then jumping. I think i am gonna take it to the dealership. Again. Last time i was in for regular service, i put it on the service sheet under requests and nothing was said about it, not even if it was taken care of. I really needed to see if other people were having issues like this.

 

and the turbo lag has been there since i got the car, when the temp. outside was in the 40s and 50s. So i cant really blame it on the A/C.
