So above 95 ish mph if you are wide open, and back off the throttle just a tad..it does a nasty shudder like it hit a gasser speed limiter then settles right back to the normal throttle position. Have I just experienced compressor surge, needeless to say you cannot hear the turbo at 95 with all the freakin wind noise. It has to either be that or some kind og fueling glitch..any ideas?

I feel the same thing with the quad at the factory speed limiter cutoff point,sure glad it keeps on truckin after thathttp://www.dieselplace.com/forum/smileys/Evil Smile.gif

Tq. converter clutch slipping?

Ive never had anything like that with my weakened predator tune......

Is this with ot without the limiter?

Tq. converter clutch slipping?

I have the 6 speed, that is not the issue, it only happens at or above the factory speed limiter cutoff point. I do not have the speed limiter anymore. If you let off the throttle slowly and not ina huge chunk at once, it does not do it. Truck has only seen around 105 mph though, have not tested it above that.

I only notice it at the limiter also,feels like the override button kicks in or something.It's smooth after the limiter all the way to 115 or so and mine has been tested many times...

Hahaha..it is amazing how easily you can get way over 100 without paying attention.

Yea I noticed that also..http://www.dieselplace.com/forum/smileys/Evil Smile.gif
