Sorry to post a new thread which has probably been answered many, many, many times before - just very tight on time at the moment as I'm in the middle of studying (hence I haven't looked through old threads) Seriously considering a KO3S upgrade / or a KO3S hybrid unit from Turbo Dynamics on my 1.8T AGU - just a couple of questions: 1) I've been told that the standard downpipe is a big restrictor in terms of hp figures after a remap when installing the hybrid or normal KO3S. Can anybody recommend an upgrade manifold? I haven't got a clue what model/make is good or will work best. 2) Forgetting that I upgrade the downpipe and just fit the KO3S (with new gaskets, bolts etc) and go for a remap (R-Tech)....any idea what sort of bhp figure I would see? I have read a bit on the KO3 > KO3S remap and it seems that 210 is the limit, with a more realistic result of around 200 hp. Car is currently running at 175 ish with a KO3 and stage 1 map....id like to break 200. I'm not just "figure chasing"....I genuinely think another 30-ish bhp will really make the car how I want it. Many thanks - very dull thread, I am sorry haha!
