Hi all
I seek advice in following matter:
My car is Skoda Octavia mk2 vRS TFSI with BWA engine, stock 200bhp/280Nm. When it had about 17000 km it was flashed by SM Chiptuning to its optimum map (stage1) giving it about 245-250 bhp with K&N panel filter in OEM intake box. Recently I have installed GFB dv+ diverter valve, have added FMIC (twin cooler system in operation similar to Forge's one), and a 3'' downpipe with 200cell cat. From time to time i get CEL regarding efficiency of catalytic converter on B1S2 sensor and i just keep reseting it. Few days ago i have installed an extender to its connection and CEL didn't came on - still under observation. Do i qualify for the stage 2 map and what gains i can see with it now??? I have in possession an Autotech HPFP upgrade kit but not mounted yet. Before going to full k04 upgrade i would like to fix other things such as clutch, diff and brakes so please refrain from what would you do.
Thanks
