It's coming up on Summertime and here in Georgia, they change the formulation of the gas in the summer monthsto try and cut down on smog yah de yah...
THIS HAS GOT TO AFFECT HOW GAS ACTUALLY BURNS INSIDE THE ENGINE

SO, the question is...

Does anyone out there have separate tunes for "Summer" and "Winter" gas?
Is there that much difference between Summer and Winter gasand is it worth getting separate tunes for Summer and Winter?
(as stated above, there must be differences otherwise the State wouldn't mandate summer/Winter gas scenarios)
Has anyone ever asked their pro-tuner guy this question before?

 

no seperate tune....run the 93 race all year

 

Does Indiana change the gas formulation between summer/winter on you guys?

 

Ask your tuner. IF they're reputable they'll tell you the truth rather than simply saying "get another tune."

 

never heard of anyone with seperate winter/summer tunes .......... only the octane level tunes
i dont think you are going to get that much of a diffrence to be 100% honest
