That is interesting since I get the same results with my V6; however, the Bully Dog does give it its best performance when running 93. Occasionally on a longer trip I will mix in 89 since its blowing right out the tailpipe anyway.MLEACH87 wrote:93 Octane 99% of the time. I can definitely tell a difference running 87. I get about 1.5 MPG less, and very slight loss of power. If I run NON-ETHANOL 93 I gain about 1.5 (no power gain I can feel).
