I have noticed that my Edge produces a transmission shudder when I drive. It is there when I am in Level 2 and Level 3. Not too bad but very annoying. At stock it is barely noticeable.

For those of you who did the PHP swap, did it get rid of your shudder?

 

I may be all wrong on this, but I thought Edge put out an update via their Lightning software that eleminated this. I never had it myself, since when I got my edge (used) I almost immediately updated the firmware and version info.

Since trading it in for a Gryphon and getting Bill's custom tune, I've never felt any kind of "shudder" either.

No shudder here.

 

Oddly enough my PHP 92 performance tune has the buck/shudder effect.
Wrote an email to Bill and hes gonna rewrite the tune.
I offered to wait back in line with everyone else as to not bonk anyones pending order but Bill said he should have one to me in a few days, without pushing anyone back! But ultimately I'm content with my 87 performance tune! My 87 perf. will smoke an edge canned 92 tune!
