Reduced Engine Performance

Can anyone help! If my car is driven at 30 after a while the reduced engine performance warning comes on but no fault code is logged. The Maf sensor has been replaced. Also the car on occasions has stalled when slowing down other occasions the rpm has almost dropped to zero before picking up to idle. The car also a a slight lumpy performance. Car is a 2006vogue

how do you find performance now ? ignoring that you had a fault before - whats the difference before the remap and after ?

better mpg ? does it change gear better after ? as in not holding gears for too long ?

thanks

sorry but only remapped to the original settings, though must say it goes better than it did! think the car may have been tinkered with before i brought it so in theprocess of getting it back upto scratch.

i have a 4.4, so economy wasnt on my mind when i brought it!
just glad to have cleared that fault.

Final update on this, found out since the car was originally built there have been 5 updates for the engine management system not only did it current fault but also have a fuel economy improvement
