    I installed the Cobb Stage 1 yesterday and am running the 91 octane map. VP Racing 100 Unleaded is sold at the pump nearby, I may do some blending and run the 93. So far I'm pretty pleased with the results. Waiting for the filter to come.

    It works for me. I'm not planning on building a race car, just want something fun to drive and surprise a few people in the process...

    I'm just going to throw this out there...
    The Ford racing "dyno" is showing almost 300tq in stock form. Most stock fost dynos I see are more like 260tq.
    Looks like ford racing is giving crank #s, which means that 90tq gain is probably 60 tq at the wheels after driveline loss

    If I'm wrong I'm wrong, but it seems too high a gain

    Depends on the number you use to estimate drivetrain loss, I always go with an estimated 15% which would be a 76lb.ft. gain at the wheels based on a 90lb.ft. gain at the crank.

    Has Cobb or Mountune considered running colder plugs along with the Fist tunes like Ford is doing with their tune?

    It's not required with our calibrations. If you run a colder plug it will be fine, though. Just might be SLIGHTLY less power.
