charged87 Posted May 20, 2014 Report Share Posted May 20, 2014 Just ordered the x4 tuner 7015. I'm planning on just using the 93 tune sct gives you on my stock 2010 gt500. Sct said 59hp 39tq. Sounds like a big gain just from a tune... does anyone on here ever just put this tune in without any mods? And how was if different from stock. Down the road I plan on getting a custom tune and bolt in my 123mm jet intake afterwards. Thanks for the help. Also it put down 476hp 471tq stock and went 12.6@113 Link to comment Share on other sites More sharing options...
Bill Hamilton Posted May 20, 2014 Report Share Posted May 20, 2014 I had the VMP 93 octane tune only on my former 2011 for about 6 weeks before I added the pulley too. The tune gave it a little better seat of the pants feel, better drivability, and increased my gas mileage about 5 to 8%. The pulley really woke it up. On my 2014 I recently added the VMP tune only. I don't plan on a pulley this time around as the car is a monster period. But like on my 2011, I got better drivability and my gas mileage has improved too. I recently got 25.5 mpg on a 200 mile interstate trip by sticking to the 70 mph speed limit. Link to comment Share on other sites More sharing options...
Hopsgt500 Posted May 22, 2014 Report Share Posted May 22, 2014 I know mine is a 2014 but I just got a basic vmp tune also, no mods, really woke it up. Link to comment Share on other sites More sharing options...
