[QUOTE="NTXRockr, post: 13333458, member: 143742"] Before my mods, I saw about 14city/22hwy or 17mpg avg on 87 octane. On 93 octane I had 16city/23hwy with around 19mpg average mileage of mostly 30-50mph city driving. After my mods (but before gear change) I was seeing 17city/27hwy and 22mpg average on 93 octane with tunes...definitely a noticeable gain from the mods (intake, x-pipe, tunes, etc) and 93 pays for itself over 87 - I estimated I save roughly $4/tank due to better fuel mileage, so the octane is worth the price jump and especially if you tune for it. After swapping the 3.15 for 4.10 gears, I had a flip to 20city/24hwy and around 20mpg average. The funny thing is on a 7+ hour roadtrip it still got 22mpg at 85mph/3500rpm but it gets great in town mileage due to the 6 speed tranny getting to cruise speed quicker and easier with the lower gearing. I also run full synthetic fluids which does help lower friction...Troy, I'll have to get with you soon about making the switch to Amsoil fluids, likely will do the engine oil first and have it ready to go for the converter swap.
