Who be a shame to retune if the following lot isn't that high. 1 Link to comment Share on other sites More sharing options...

Ive no idea if these barrel mix's have additives in them, which is possibly why poeple have had fuel line & filter issues.Get into the stuff... its awesome, boost up and have piece of mind.CheersChris 1 Link to comment Share on other sites More sharing options...

Would solve a lot of these arguments! If you could do a quick change to your lambda value then it would make mixing fuels safer. The Holden's now have that nice ethanol table in their calibration too which is useful as an OEM type reference to ethanol mixtures and their corresponding lambda.

dre Resident idiot. Donating Members 2,068 Member For: 14y 3m 2d Gender: Male Location: Melbourne Posted 22/03/12 06:10 PM Share Posted 22/03/12 06:10 PM I changed over to E85 before the car got sold, all I can say is WOW!I'll be getting another F6 soon, first thing I'm going to do is get it onto E85. So much more responsive all over the rev range, much nicer to drive.Ended up with 391rwkw, gained around 40 just from the 85. Link to comment Share on other sites More sharing options...

Tuner waved magic wand and 45rwkw gain. Link to comment Share on other sites More sharing options...
