4 bar fpr

[prowler]

hi guys. does it really make that much of a difference if you fit a 4 bar fpr on a remapped 1.8t with k04 turbo.
coz jus checked mine an its a 3 bar. am i missing out or what??

you'll only really see the benefits if you have a uprated fuel pump, injectors and 4 bar fpr. As it can then be mapped to try increase the boost and have a strong enough fuelling system to get a good Air/Fuel ratio
