Have paid the $150 to "upgrade" my BAMA SCT X4 tuner. Now have "tunes for lfe". Selected two tunes for my 2013 GT, a 91 octane race and a 93 octane race. A previous 91 octane tune was on the ECU when I downloaded the new one. At the start of the download a page of user setable parameters appeared. Speed Limit, spark advance global or window, engine max rpm, tire size etc. The values in the spark advance showed no change from stock, the speed limit was off and the engine rpm showed 7,000 rpm - up about 200 from stock I think. Does anyone know whether this display shows values in the tune being loaded or the tune already on the engine? Thanks.
