You can't really compare numbers from different dyno runs & different dynos. Mustang usually reads lower then DynoJet.

Even with the same make, dynos at different locations car generate different readings, so it best to do a baseline then a moded run on the same machine as close together as possible & use the delta to tell you if you are going in the right direction. For what its worth my best on a Dynojet was 319whp stock 94 octane, 375whp with a JB4 335is Map 6, best torque was 414wtq. this was on a 95/96 octane mix. Car has a JB4 & ETS 5” FMIC.

Just started to experiment with E85 & have a 35% mix with 93 octane. No dyno yet but the mid ranges feel stronger. I hate the “feels stronger'” stuff because there could be some placebo effect in there so will wait for a dyno run before I decide to swap racing gas for E85.
