ok,this is for my cousins 95 eagle talon tsi.....as far as mods he has the following...

greddy fmic
greddy hard pipe's
greddy type rs bov
walbro 255 fuel pump
and he has a 14b turbo

ok this is the problem we are having.....first gear is pefectly fine...second gear right before he reaches full boost the car cuts out then comes back,it will not keep pulling.almost as if the car shuts off.we are lost.we have checked for leaks,tightened the bov tension (thinking maybe it was boosting to much and releasing?) and we cannot find anything........can this be a fuel injector prob?we pulled the fuel filter off today to check it and it was pretty nasty,but i am just wanting to get some opinions so we can be ready tomarroiw when we put the new filter on.any help is appreciated.thanks
