six appeal 53 Posted April 18, 2005 Report Share Posted April 18, 2005 Hi there guys, I have just aquired a brand new 4 bar fuel pressure regulator (as opposed to the 3 Bar standard one) for my OBD2 VR Highline.I've been led to believe you can just swop these over and will get a very slight improvement on throttle response (especially when running high density air filter and shrick! as I am) Has anyone had any experience of fitting these? Can I do it without chipping the ECU?Thanks in advance.Simon. Link to post Share on other sites

six appeal 53 Posted April 19, 2005 Author Report Share Posted April 19, 2005 Spoke to the VR God, that is Vince at Stealth, and he's said on an OBD2 car, its not a problem as the Lamda sensor can adjust to it! You may get it squirting a little bit of fuel in too much on full throttle, but not a drastic amount, plus with my mods he recons I may actually get a better throttle response. WOOHOO!Ps. Part Number for a 4 bar regulator from VW : 078133534C at about £55 Link to post Share on other sites
VRmonster 1 Posted April 19, 2005 Report Share Posted April 19, 2005 might have to call ecp and see if they have one cheaper, lol. Link to post Share on other sites

simey 0 Posted April 20, 2005 Report Share Posted April 20, 2005 4 bar fuel regulator is a must for s/c but as power has increased I need bigger injectors to deal with it now......... Link to post Share on other sites
six appeal 53 Posted April 22, 2005 Author Report Share Posted April 22, 2005 Have fitted mine now (2 mins job!) and I must say I CAN tell the difference, despite the car not being remapped to suit!Throttle response seems to be a lot more responsive (revs more freely). So I'm happy with the results, now just need to get Vince to map it! Link to post Share on other sites
