I had my car mapped about 2 weeks ago by Mr F.
It made 330/321 on a VF23 with FMIC, Apexi induction kit and Walbro fuel pump
It has been going great and today when overtaking a granny im half way past and BANG car totally loses power like hitting the brakes pretty hard.
Only seems to happen when im accelerating hard and the car hits 4000rpm. If i accelerate gradually past this rev range it does not fuel cut.
It does not cut out just loses alot of power and then i let off put my foot down again and it did it again.
I have a full tank of fuel
What causes fuel cut? Any other tips as it could be pretty dangerous as im sure you would imagine when your half way past a car and you lose all power
