Fuel Pressure Regulator for VW Golf Audi 1.8T Turbo Gti

[golf-sib]

4bar vs 3bar means you get 33% more fuel, if its a custom map then they will account the current 4bar reg that you fit on and adjust the injectors accordingly in the map.

However if its just a generic map it may have been written for 3bar in mind, this means the additional fuel will benifit in some parts of the map but reduce performance in other parts of the map.

Also what engine is it, I know the AGU stock injectors max out at around 235bhp @ 3bar, and the AUM injectors go further @ 3bar, all depends on what power your after?

Also keep in mind just upping the FBR isn't a means of increasing performance as maps are written lean and rich at various parts as these factors have an effect on max bhp, max torque and how the turbo spools/boosts. Plus its usually better to change injectors to a higher cc than just upping the FBR reg as the injectors won't love you for running them at max duty!

gr8 info thanks, so all in all it isnt really needed unless your going for big power, its an AGU, lookin to get a k03s possibly k04 but theres loads of sh!t i wana do first, really wana just map it with the k03s and mods for now am i right in sayin could see around 200 + bhp on a stage 2 map with the reccomended mods

Think it depends on your map tell the truth revo say fit 4bar fpr with stage 2 map with ko3/s remap. Sure APR do too I've got one but will fit when fitting,255 fuel pump, Saab yellow and 3" maf for remap.
