Hi guys, I am a new S4 owner, maybe you can answer this for me. I have
searched all over Vermont and cannot find 100-octane gas. If you guys know
of any places please let me know. There is a place right down the road that
sells 105 unleaded.
Can I run 105 octane in my stock 2001 S4? I think it is a pre 01.5
because of the early style badges but I do have an esp button. I have not
had the chance to look at the ecu or shifter yet. I am on the East Coast and
have 93 readily available.
I am thinking of purchasing a chip soon and am starting my research. I
plan on getting 93/100 software. I was told I can run the 105 with chip in
100 race mode. Can I run 105 stock now? Will this do anything other than
keep the knock sensors form activating early? Is there any significant hp
gain?
There is also 100 Avgas and 110 race fuel available locally but it is
leaded and I hear that this is very bad for the oxygen sensors?
Anyone have BTDT or experience with chips and can recommend one that
you feel worked well? I am leaning toward APR but am considering MTM, AWE,
Achtunig, etc...
Thanks for the help. -Bob
