hey everyone not quite sure what my problem is today but i think it might be my fuel pump starting to go ...what happens is that when im starting to go up a hill in say for eg. third gear 4800 rpm it feels like it isnt getting enough fuel and begins to slightly shutter and carry on ....i know it isnt anything to do with tuning or my k04 turbo it comes on boost hard strong and holds it all the way to redline ....and i changed my fuel filter around 1 month ago it is a walbro 255l custom setup i am unsure of injector exact size but im sure they are more than enough for my power figures... any one ever had this trouble and do fuel pumps this new stuff up ...it has run like an absolute dream for the last 7000kms with the k04..any info would be a help thanx guys
