Not sure what everyone else is getting for fuel consumption but mine has increased but due to the fact I been hitting boost to make bum dyno happy
, it feels fast imo tho I get bulk wheel spin in the rain doesn't help.
P100 is only 10% ethanol
in regards to E85 I have mates in their R32 shitters who run E85 only and they didnt even change the fuel lines just injectors/pumps and tune, been going
strong for few years now
