Hey guys, recently bought a r34 gtt and I've found when hitting high boost the engine light flahses on and off until i let it off boost.
It has a Z32 and a power FC and is on half a bar of boost.
Previous owner said it is tuned to run on 98 and I put a quarter of a tank of 95 (couldn't find 98 at the time), could this be the issue as the tunes set up for 98? or could it be faulty AFM or something else? I'm scared to put my foot down in boost, don't wanna break anything.
Any help is appreciated
