Question Explain this?

Ok, I think I have captured what I have been trying to verbalize. A surging or pulsing of the rpms when tcc is locked at steady throtle.






Please take a look and give opinion.

my turbo, or any boost MAYBE, rally hates to be locked up and into. thats why i set mine to unlock at like 50 percent throtle. That was sometihng i first changed when i went boosted, granted a loaded turbo gets into boost easy. But like going 70, and using the cruise control to speed up to 75, i hated the way it felt. I like it to unlock.

But im unsure about the radix tuning set up.

Bill, at 7100 in 5th, my truck surges as well, only difference is mine is the 5 speed. Does it feel like a slight miss, but them when you accelorate a little it just goes away?

Yeah, mine unlocks at 50% TPS @ 75mph. You can see in the top screen-shot that I am going into PE but barely in boost.
I didn't even feel this today but yesterday under a heavy load (going up a big hill (that's mountain to you Eastern guys)) it was very noticable.
