    I'm getting my Solo HFC and Catback installed in a week or two, so I'll need to remove my Superchips tune due to the HFC.

    I have the cortex tuner. Currently I'm running the Vararam 93 tune. It has the option for increasing your shift points by 100, 150, 200rpms, etc. The hp/tq graph cortex has out for the tune leaves me to believe that when you shift you want to try and be as close to 4200rpm as possible in the...

  14. PCM Tuning / Dyno Results
    I'm researching and planning on purchasing this for a couple of reasons. A.) I plan on selling it later to receive most my money back as I would like to upgrade to cams and headers. After this, purchasing a better tune from Livernoise or Vector will happen. B.) I have a vararam intake, cat...
