hey guys,
I have just installed a fmi on my stagea its drives fine when i am driving normal , but if i accelerate hard the engine is cutting out at around 3500 rpm and then picks up again ,still cuts out but not very
noticeable . It feels like i am changing gears on an auto when the first cutout happens at 3500 rpm. I haven't changed the air intake hose still factory rubber type .
Thanks in advance
