I'm ordering the C&L Intake system with SCT X3. I'm getting it from evolution performance. I'm stuck at the options they ask me to order it. Here's the options i'm stuck at.. They ask for first, second, third tune for octane. I don't know what kind to get. Also they ask for gear ratios... Does anyone know the ratios on a Stock v6 pony package mustang? Thanks

when i got mine u put stock in where it asked for ratio and as far as tunes i got a

87 perf
93 perf
93 mileage

right now im using the 87 perf because 93 is 3.98 a gallon right now

 

they have a 100 octane tune on the xcal3s'? there is only one place in town that sells that here...i remember, like, 10 yrs ago, it was 3.00 a gallon...lol, it is probably 8.00 a gallon by now. :P

 

I see, SoI shouldset it at87,93,93 octane? Also does anyone know the ratio on 07 v6 Stang? Is it 3.31?
