Hi i bought an Evo 7 with a Greddy Emanage Blue already installed. Ive noticed its very hard for me to crack 300km's out of a tank even when im not boosting it hard. Ive spoken to a few people and they reckon my problem lies in the Emanage being the problem. I just want to know what sort of mileage everyone else is getting, stock ecu and with piggyback/standalone.

Cheers
