So over the last few months I have been getting 35 mpg on b20, i go to about 1/4 a tank and fill, calculate milage manually. Including a 600 mile trip to cali i regularly do.
I have a new bosch maf, and 02 sensor (bought at reputable store) new fuel filter and getting a code saying 02 senor is rich...
I also changed my egr with a rebuilt one and no change.
Dog collar on the upper hose and new exit hose out of the turbo
Car has a newish vnt17 lowered on gti springs has a rebuilt 5mt.... (Make sure to always use thread locker on new axels)
And new brakes where i greased them myself (i work in a subaru shop part time as a hoby)
Any help to get 45mpg again... Also has a tune with a 2 bar map and racaro leather seats.... Save weight?
I am thinking its time i clean the intake system, i see active boost, and it hasn't changed, i do about 10 psi actual boost at 75mph
