Here my 3rd gear and 4th gear logs. Audi S3 210 hp (APY with ESP). It's remapped. It has Forge 007 diverter valve (with yellow spring) and silicone TIP (from ebay). What can the problem be? There are lots of CFs as shown. And engine load goes lower on higher revs. By the way there is no fault codes. Turbocharger (k04-022), exhaust manifold and MAF are brand new and genuine (from vw-audi dealer) Injectors tested on flowbench, all ok. FPR checked and renewed, but nothing changed. Catalytic converter, n249, n112, evap and sai all deleted with no CEL. Bad fuel pump maybe? Your opinions? Thanks.
