super-roo17 Posted December 8, 2012 Share Posted December 8, 2012 im looking to upgrade the LGT to significant power 300-350. but i want to keep the mpg's around the 18-20 area. with the realization im going to loose a few miles to the gallon. im looking to see what people with 300+ hp get for mpg's!

super-roo17 Posted December 8, 2012 Author Share Posted December 8, 2012 Do you guys have the Cobb Tunning access port? If you do have you tried the mpg saver mode and is it what they make it out to be? Link to comment Share on other sites More sharing options...
Nrw Posted December 8, 2012 Share Posted December 8, 2012 Miles per gallon is overrated. Smiles per gallon is all one should worry about. Link to comment Share on other sites More sharing options...
bigleben Posted December 8, 2012 Share Posted December 8, 2012 Ive tried the OTS economy map and it didn't change much. Honestly, a good tune with a highway cruising speed below 3k is the way to go. Otherwise everything is in the right foot control. Hard to acheive but once mastered, you can see fuel "economy". Link to comment Share on other sites More sharing options...

Propane conversion is difficult to come by here in ireland, not many places give access for LPG vehicles.... :-/ I'd save a fortune! Link to comment Share on other sites More sharing options...
