hi guys

I have a 2005 ba mk 11 xr6turbo 6 speed manual. it has a cold air induction and has been dyno tuned. I am having a few problems with it, when I pull up to a set of lights and shift down gears the engine revs very low (bounces beetween 300rpm and 1000rpm) and sometimes stalls. the car also strugles to pull in 3rd gear and above, it gets to about 3000rpm then revs out but stops pulling, its like it loses power but continues to rev. Third and final thing is sometimes if I boot it in first after I back of or change gears it revs like sh*t and sounds like its droped a cylinder or something, it will continue to run like this for a couple of minutes. Ford recently serviced it and change the plugs and coil pack but that hasnt fixed anything. Any tips or ideas you guys can offer would be greatly appreciated

Who tuned it? Has it started doing this immediately after the tune?

did you set the tune back to stock before taking it in to ford? if you didnt, they would have. dont give it revs unless you want to blow it up. either reinstall the correct tune (if its a flash) or go back to your tuner asap.

either way dont drive it hard as it needs to go on a dyno to check the afr's etc....
