Slow Rpm Increase, Lack Of Power, Very Slow At Gaining Speed - Help

2008 335i 6MT, 139,000 km

So I am just about ready to throw my car off a cliff

A few days ago, I took my car to have my summers (18" BBS RX209 on DWS tires) swapped off for my winters (19" Style 225s on BLizzak LM-25). As soon as my car got back to me, I felt as if it was a completely different car. Ive been having HP issues for a few weeks now, but this was drastically different. I would step on the gas, and my RPM would barely climb. My car is really slow now an I have no idea what direction to go now. After 3000RPM, the car barely increases in speed. after 4000RPM, the power feels like its completely lost.

I searched up to see if I have a slipping clutch, and as per the videos on youtube, my clutch does not behave like that.

I have has my intake cleaning done 3 times now. My spark plugs were done 2000kms ago, my coils 2500 kms ago, My injectors 6000 kms ago, Fuel Pump recall is already done, my boost solenoids were replaced in May 2016.

Today when driving to work, when I gassed on the car, I started to smell a strong scent (like deisel), though there were many trucks and school buses next to me, so I dont know if it was from them or me (but it was really strong). I tried to do a 3rd gear start up, but it was about to stall. The car gets up and goes on 2nd no problem. Last night, I was reversing into a spot, and my car nearly stalled out.

I am thinking of putting my summer tires back onto the car, just to see if its the winter tires that are making the car slow. But in all honesty, I have no idea what to do now, and im losing my mind.

HELP
