Could be coincidental but, I have fitted a set of tfsi coil packs today and taking it for a test run. The car seems to be pulling better and running better but when it comes onto boost it seems to hold back then take off. I have a forge 007p dv with the 1st stage uprated spring (yellow I think) My car has a stage 1 revo map. I am thinking the old coils were on the way out and holding the car back a bit. I have run a scan and not getting any faults. Can anyone advice if you think it is the dv holding the boost back / sticking or could it be the coil packs ( which seems strange as it feels so much stronger) Thanks all.
