been collecting together bits for my AGU 2000 1.8T for a ko3s swap for my ko3. Was planning to change the downpipe and custome remap. However having just spoken at length to a Custom Code dealer in brighton, he was convinced it wasnt worth swapping the turbo. Said the early model AGU A3's ECU's wernt very good to program (without VVT), and that id be much better changing the full exhaust, a stage 1 remap on the k03 = give me around 220bhp. I wasnt so sure on this but i dont work at a rolling road tuning company. I have to speak to custom codes also as he thought this remap (with k03s) would fall under a stage 3 remap, whereas i'd heard stage 2 elsewhere.... Anyone got any oppinions?
