Bogging/Hesitation

[Redcallen]

When I try to accelerate hard from a stop, the car accelerates very slowly. It feels like i'm trying to go uphill with 10 people in the car. If I back off the accelerator its not so bad. This only happens after the car warms up. Before it warms up the car runs like a champ. Any Ideas??

check your pipes for a vacuum leak.

I checked all my vacuum lines and pipes. No leaks.

Mine does the same thing.. if I have my foot halfway down and allow the boost to build up then it's fine, but if I floor it, it bogs down and can't get anywhere. I figure maybe it's getting more gas than it needs at that time or something. I tried two different maps with my AFC and one makes it bog right after 4K rpms even without my foot on the gas that much, easing it into it still doesn't help.. but the other map doesn't give me any problems except if I try to floor it, but the only reason I floored it the one time was to see if it would bog, which it did. From that I just figured it was getting more fuel than it needed and made it bog down.

Mine is similar. If I only put my foot down 3/4 and let the boost build, it goes strong. But if I put my foot all the way down, it hesitates a little bit.
