Default Questions concerning 5-bar FPR and Fuel Injectors with KO4 Kits...more inside

what are the pros and cons of using a FPR versus new larger fuel injectors(assuming the kits are optimized for each)? and more specific the pros and cons of drivablilty & gas mileage versus power and performance.

Default I'm running stock injectors..

with my Wetterauer K04 kit without any problem. I have not had any issues with the mostly stock engine components (injectors, plugs).

As for fuel/driveability, I have not noticed any difference... I still get avg 26mpg on a 2 hr trip @ 75mph.

Default The cost of a FPR is much lower then the cost of 4 new injectors

the chips for the K04 are tuned using the 5 bar fpr. The only thing you will notice is that the cluster display will be off since it uses injector pulse to calculate that.

Default Do you know how it is done?

I just found out how to adjust my idle speed with the vag and would love to be able to change my cluster reading since I am running 440cc injectors at this time.
