Re: Mk5 gti stalls out at high speed
It's HPFP sensor, its probbaly cracked and this happens when it hot.
replace HPFP and the problem will be gone

Re: Mk5 gti stalls out at high speed
why do you need a new pump?
Did you check the sensor on the pump for cracks?
Lastly unplug MAP Sensor and see if the problem persist...could be that too

Re: Mk5 gti stalls out at high speed
did the pumps go through the Cam Follower?
Maybe the Mafless tune is your problem!...anyway as said check the MAP Sensor on the throttle pipe

Re: Mk5 gti stalls out at high speed
Do u have acces to vcds ? If not get urself 1 then log the car and see whats the problem. im also 100% sure that if u check fault codes it would have definitely threw an error dont waste money buying pumps ,coils and plugs when it might be something on the opposite end of the world thats broken ...and if i may ask y do a mafless tune on a mk5 gti with ko3 turbo ? Or are u running big turbo setup
Log:

rail pressure actual and specified
Fuel pump pressure actual and specified (intank pump)
Cylinder misfire 1,2,3,4

And ur lamda ...post the logs and some1 will assist
Original vcds is R7000 1st tool u should buy before even purchasing a spanner.... and pirate is R800 but also does the job

Re: Mk5 gti stalls out at high speed
R u running a cold air intake?
I think ur car DOES NOT have a mafless file coz if it was a mafless tune then whether its plugged in or not should not make a difference coz the maf DOES NOT work on a mafless tune

Re: Mk5 gti stalls out at high speed
Those mafs are finnicky things. Any oil residue or debris build up and your readings go haywire. Get some electronic switch cleaner and clean that maf sensor properly. Don't be stingy with it. Make sure though that you don't use q20 or any other liquid. The switch cleaner is mostly alcohol and evaporates immediately, resulting in no remaining residue.
