Okay so, I've had an issue with my Legacy from day 1 (2003 BL5 5speed turbo)
Issue only happens on track.
Gives me a few trouble free laps but then down the straights it cuts power.
It was alright to start with but just getting progressively worse (With the new engine, EJ25, EJ20 heads, twin scroll turbo etc)
Now barely gives 1 trouble free laps, cuts power, smokes A LOT (Black Like overfuelling) and is just an all round pain in the ass.
Last trackday I done some logging on a scan tool. Coolant temp only ever got to 100 degrees once, IAT was 25-30 so they're not too bad.
Tuner has noticed that one the data logging, it seems that randomly, my accelerator pedal position reads 100% but the throttle position just cuts to 0%.
Anyone come along this kind of problem before?
Car is running a stock ECU just retuned, however I've been having this problem since it was completely stock.
