hi all, i recently had my car chipped by jayson at chipped uk the car was great running really quitley and smoothly and was very responsive in all gears , it has been about 2 and a bit weeks since having it chipped, but now the performance isnt the same let me explain, the car feels alot louder and sluggish through the revs and the smooth ride has dissapeared this is how it drives most of the time but on the odd day it reverts back to being really quiet extremley responsive and very very smooth with loads of torque and power. the car has been serviced under 1k ago 5 green bars left and no fualts showing on the bmw diagnostic equipment, and i have just had it m.o.t'd and its showing the best ever emissions levels. now i am quite certain its nothing to do with the re-map, but i do know their is a problem and its really pis**ng me off
pls pls pls pls can anyone help???
