Just looking for a bit of advice on my cupra, it seems to have lost a bit of power and takes a bit longer than usual to spool.
When I first got it it was hella aggressive and would pretty much spin going into third with a brisk gear change, Now it seems to be delayed when you put your foot down and seems to do this regardless of rpm or gear. Lets say I'm at 2000rpm in second, you mash the throttle and you can hear it spooling but nothing major happens until around 3k and at 4k it's like the boost is tapering off, whereas before it would pull like a train from 2k-4k and then hit the vvt and put a huge smile on my face.
The car came to me with a warped cylinder head caused by a cracked coolant flange. I got the head skimmed, replaced the DV and deleted the N249 and N112? next to it? silicone tip 3" decat downpipe. Here are the codes, note that I deleted my secondary 02 sensor so you can ignore some of the codes.
17526 - P1118
17524 - P1116
17748 - P1340
17522 - P1114
17511 - P1103
The two that concern me are P1340 which says I'm likely to be a tooth out on the timing belt after re-installing the head. Also P1103 Which is complaining about the performance of my primary 02 sensor. I have the free version of VCDS and managed to clear the codes going through the different options, so I can confirm these are current codes and p1340 is not an old code from when the oil ran low and would have lost a little pressure, which can also flag this code.
Car runs smooth at idle and pulls really well but I have been told it will do this with only being 1 tooth out. Any help would be much appreciated.
