Fuel cut I think

[Tsisaman]

Ok so I've looked and looked I think my problem is fuel cut but can't seem to find any answare as to why it would be.

So here's my problem every now and again when I'm under wot my car will fall flat on its a** aka feels like I'm hitting a brick wall. I just picked up the car a month ago so I don't know what's all been done to it. I do know it have the wb255 fuel pump aftermarket fpr, don't know injectors or if its been tuned for anything. It's running 15psi on a 14b. Also if you need to know its a 94 tsi awd. Any help would be great.

A big fuel pump won't do you much good unless you have bigger injectors and a tune to pull it all together. The stock pump will pump enough fuel to feed the stock injectors just fine. I'd look at getting a tuning solution first.

Thats what I was thinking all I know is what the guy I bought it from told me. He never said he put bigger injectors on or anything but then again he may have forgot. But if I do find out that I have bigger injectors what all would I need to tune the car. Just the EPROM ecu and ecmlink

My car did the same thing. and it was because the ecu was reading to much boost on the fuel curve so it was making its own rev limiter so to speak. i got an hks fcd and fixed my problem there. but i was running 16lbs on a 16g. my car no longer cuts out at 35oo rpms. it rolls up to around 7 before it starts to hit rev limiter.

Check all your grounds i had exact same car and same problem dont just make sure there tight unhook them and check for corrosion thats what my problem was and i spent lots of money on injectors,plugs,pump thinking it was the problem then i went threw all the grounds found corrosion cleaned them up with wire wheel and car ran perfect!
Hope this helps good luck
