I was playing around today, i tested my car with a g-tech meter and then i was spinning around alittle. Then a friend wanted do go for a ride and when i gave the pedal the floor it went to about 3500 rpm and then just died like it didnt get any fuel, but i had over 20 litres in it. Does anyone know what could be wrong?

 

maybe something called fuel cut... do you have stock ECU ?
if yes..then you must of boosted too high...

 

yes i was expecting that to, but my car is completely stock.

 

could have been a cold day in sweden...only take like 12psi to hit with stock ECU....it's most likly what happened

 

This day was the warmest day this year and the warmest day for me with the car so it can't be that.

 

were you turning to the left?
My car used to cut out on SHARP left hand turns. If you were going left, check your fuel sock.

 

dude you can speculate all you want....
you need to get a boost gauge...

I still say its fuel cut
