Thread: TB values for Cobra Jet Twin 65mm in 2011 GT500?

  1. #1

    TB values for Cobra Jet Twin 65mm in 2011 GT500?

    Ive tried my known good values from 07-08 shelbys for this TB, but in this car if makes for a bad dead spot just past 0in vacuum. I have gotten it very close just doing some small changes to stock values, but I am still getting a bit of throttle osculation under moderate throttle.

    Anyone have some values that will get me in the ball part for this setup?

    Car is 2011 GT500

    That's from SCT, their rows are backwards from HPT. Top is bottom. Bottom is top.
    I like the twin 67mm TB data better. The drivability is better to me. If you're still having oscillation, you need to check your torque/inverse. Make sure you have the oscillation switch disabled too, btw.
