also i dont have the factory boost sending unit hooked up. the wiring showed that it went to the gauge only.
what rpm does the stock trim start to boost?
when does the fuel up vsv open? it does not matter if the fpr has vac or not.

No diagnostic codes stored in the ECU? The CEL doesn't even come on for most of them so if you haven't checked then do so. There's a how to in the MKIII FAQ section.

no cel and nothing stored. so????
i am thinking it is a boost leak but cant find it.
do you think the video resembles a boost leak?
when i turn the steering wheel it does not idle up. the ps pressure switch is working and the lines are clear.

Something just hit me....


Why are you running a second fuel pump, inline with the stocker? I'm assuming they aren't plumbed parallel.

i put in a second pump (intank) because i was thinking that the inline walbro (up on the fender) was loosing suction due to it is higher than the tank. so i put it in there.
started the motor (with 1 pump going) let it warm up, then when the stumble hit i turned on the intank pump. there was no difference between 1 or 2 pumps going.
