All,
Currently have Vishnu Stage 0 Sig, heading for Stage 1 Sig at the Georgia Tunerama this week, tuned by Shiv himself. But, winter gas is coming, same "octane", but different combustion/evaporation characteristics. Is there any potential issue having the car custom tuned with "summer" gasoline, then moving to winter gas?
Thanks!
Doug in Cincinnati, where we have seasons...

 

Doug, I'm out in Colorado (where we have seasons AND a football team! just messin' dude :-)

Last year winter gas threw up a few SES lights on my( then) stock EVO, but no real problem other than knowing that crap is running through my baby's veins.

Good luck with the XEDE, I'm diggin mine so far (since about May)
