shaneirish Posted July 10, 2015 Report Share Posted July 10, 2015 I've been advised to order the 4+ and 4X tune for my 2010 SHO. There is no 4X tune listed on the Livernois site. The 4+ also has a disclaimer "Use at your own risk". Please advise, thanks. http://www.livernoismotorsports.com/products/LME%252dAIW-2010%252d2012-SHO-ECOBOOST-TUNER.html EkbergJen and RudyFloum 2 Quote Link to comment Share on other sites More sharing options...
mval Posted July 10, 2015 Report Share Posted July 10, 2015 shane: basically they all come with same run at your own risk. A lot of guys running 4x93 for quite a while. But i'm on the conserative side & only tuned mine abou 3 months ago & am running the 4+93. no issues whatsoever. i also got a 4+91, as some guys run this when using winter gas. they run 93 but with this tune if they have an issue with car not as peppy as should be. we all know that winter gas is crap as gas mileage drops a couple miles per gallon when using it.

mjhpadi Posted July 10, 2015 Report Share Posted July 10, 2015 I've run the 4+ and now the 4X year round with no problems. I think if you call Livernois you will find them very helpful in answering all your questions. The only downside of using the 4X tune is the requirement to change plugs, sensor, and the 160 thermostat, but again, easy changes and worth it for the performance gain.
