    Hey Guy, Sorry for being a dick yesterday, just fed up with the wait for the truck and need some more positive in my life. This helps! big gains, I assume there shop is quite a ways above sea level?

    No worries.

    I try to be honest with you guys.

    I don't know a lot about JMS. I'm not sure where they even run their dyno.
    I'll be honest the red flag to me is that the dyno run uses mph on its x axis and not RPMs. I asked about a dyno run with horsepower and torque vs rpm but they don't have it.

    Weird right? Is that a red flag? So are we seeing PEAK horsepower gains and the actual curve on the RPM scale is only minuscule? 60 RWHP is huge but it's not very useful if it's at 6000 RPM only.

    I don't know those answers. Maybe some other folks can chime in with their knowledge.

    I'm going to be the guinea pig. It's 309 bucks. For a few bucks there isn't much to lose. I ordered it. I'll let you know what it does.

    Ok well here's my update. I bought the boostmax and had it rush shipped. I got it last night.

    The instructions are generic and are for a regular f-150. Whatever... I know my way around an engine... so I pull the engine cover. Locate the MAP and TIP sensors, pull the harness off and find that JMS sent me the wrong thing.

    The harness they sent me does not match up to the Raptor. I called them but apparently they are closed on the weekends.

    So far they aren't off to a great start. I'll see how they recover.
