    I have a 2007 Mustang V6 Convertible Premium with Pony package less than 80k miles. Just installed a new SR Performance CAI and Throttle body Spacer. I bought a SCT X3 3000 Tuner and upr sent me 3 custom Tunes. 87 performance, 91 performance and a 93 Performance tune. I'm running the 91 right now and love the added mods. I sent an email asking what was set and received the following back:

    Basically all 3 tunes correct air fuel for the car, up the rev limiter to 6350, firm the shifts up a little (more can be done on the handheld), and spark changes per tune for the fuel.
    Max Spark
    stock = 17.78
    87= 20.28
    91= 23.78
    93= 32.00

    I wanted to make a few adjustments when I load the next tune but have a few questions I am hoping someone here could help me out?
    I'm wanting to feel the shifts in the auto trans a lot firmer and the shift point maximized in the 91 tune and especially the 93 race tune. I can make several changes with options before loading the tunes, but being new to this type tuning I am not sure what settings are best to get the maximum results in performance without over pushing the car? Anybody have any experience here that could possibly help me out on the info.
