Help- engine problem..

Have a 2011 335n55 Msport. JB stage 1. Car has about 58k miles, I know.. ha ... Recently the car when trying to accelerate lagging horribly and accelerating slow. The car is accelerating, but not as quick as it was or should be. I recently replaced charge pipe about two months ago, due to a crack in it, and an oem charge pipe was put back in,i believe 1 or 2 spark plugs were changed and 1 coil, car was running fine and great like its supposed to after. Now, car's performance has dropped dramatically. Being car is out of warrenty, if bring to bmw, they will knock me over the head most likely. Any one have issue's with this before. Could it possibly be the JB? sparkplugs or chargepipe again? ... Ive also seen my gas getting eatn up. I will fill up, and maybe, 10-15 miles, quarter of tank is gone, and that's not even gettn hard on the car.

any help appreciated thanks..
