    Whipple tune aren't good.. don't waist time and money. Get a good email tune or dyno. I finally got my tuned through email and it drives good without any issues...

    Do a search for adding a SCIAP sensor. It makes a tremendous difference tuning these out.

    We have a pigtail kit.

    Does your kit include the wiring and instructions on how to wire it into the ecm? If it does I'm sending my customers adding blowers to y'all to get these!!!

    OK, sending the link to a gent in Canada right now as he's doing a blown cam swap into a jeep. Already told him he really needed to do this. Nice to know there's a simple kit for it now.

    You can often fix that in the DD tables. Take a bunch out and keep things smooth. I often have to do that for blower installs. Usually lighter throttle though for the drive through window or stop and go traffic scenarios.

    You've got a couple of codes you might want to check into. Might need a new pedal from the looks of it. Think there was an update for flexing too.

    I still stand by that SCIAP sensor is what you need.
    The ECU does not understand that it has a supercharger attached.
    It believes that 50% Demanded torque roughly equates to 50% throttle
    In a supercharger case, this results in no vaccum and then all the boost.

    The computer then in some cases shuts the throttle because the actual torque is way to high for the pedal demanded torque.
    With the SCIAP sensor, the ECU can modulate the throttle and torque based on the amount of air pressure just behind the throttle blade

    Yes. This is what the SCIAP sensor will fix. IT makes a huge difference.
