Question Fuel Problem

Hi,
Noticed a lack of acceleration with our Hawkeye Sport Wagon, took it to local Subaru dealer and the fella asked if we used Morrisons fuel as Subaru's dont like it apparently. Well we had been using Shell 95ron but topped it up at local garage but dont know what this small garage supplied. Anyway he said the problem was that it was pinking although you would'nt hear it and the ecu was retarding the ignition to prevent that hence the problem. He added a program? he called a Pack File so now it will run on any 95ron fuel. Should I revert to using Shell though as although the acceleration is much better it seems a bit uneven at tickover atm

Cheers

Al

Re: Fuel Problem

God knows what hes added, turbo'd models should always be run on 99ron even standard (speak to subaru employees off the record and they will tell you that), unless specificly mapped for 95, theres a fuel thread sticky in the general tech section have a read.

Personaly i'd get it to a specialist with a rolling road and get them to give it a full health check. see what the fueling is doing and what he's actualy done to it.
