I have a 5 bar FPR, and want to pu tit in my 1.8T, I have a k03 sport turbo, and no chip. Would it make a difference if i installed it?? would it hurt anything? I've heard both...but wanna find out some more info.
I put on a 4 bar when i installed my K-04 just to play around and my car ran real rich.At 5000rpms when the chip was really dumping fuel the car fell flat on its face.You wont have any fuel problems with a chip and that turbo.
If your running that much boost out of a K04 to need bigger injectors, Your running WAY out of it's effecncy or in a New Beetle.
K04 turbos run best at 1.4-1.5 bar or so any more and your just spinning your wheels so to speak. The turbo would be way out of it's effecency zone. I wouldn't think you would need the 5 bar EXCEPT maybe a passat or a New Beetle with stock injectors. The OEM stuff works fine with G/J setup.
