BMW 335i Feels like it's isn't as fast and overheating?

Hi everyone I just finished replacing my alternator 2 days ago and have been driving around for a day now, after I got off work I noticed my car doesn't feel nearly as powerful like less torque and horsepower.. i love in socal it got up to about 102 here today, I got a car wash.. then drive home and that's when I realized it's not feeling as touchy. When I rev my car and push down all the way on the gas it usually revs up to 6000 RPM but it only goes up to about 3-4,000 RPM.. It's really annoying because I know how my car is supposed to feel and it's not feeling up to par with me.. could it be from the car wash? The heat? The alternator? I really don't know I hope someone can help me. Thanks.

The heat will definitely cause a lack of power vs the nice cold weather run we've had. The turbo charged air isn't cooling off as well through the intercooler and I was lagging today on the way home from Upland. That being said, you still should be able to get the rpms up between the 6000 and 7000 range. No Check Engine light or anything happening? Limp mode illuminating? Did you removed your Charged Pipe at all?

If you can only rev your car to 3-4k you have a serious problem. It should bounce off the rev limiter when you press the pedal all the way down.

As previously noted, no check engine light?
