Confused mate, Phill, don't you already have a remap from your cams?
I am running an evolve remap for my cams yep. And it was perfect. After the cat removal the hesitation is present at 3k rpm.
D4dawg had the same problem as me, after decat hesitation at 3k rpm. His issue was resolved by a custom remap.
Imran at Evolve says he can't do anything to resolve this issue and I should remove the decat pipe if I can't accept the flatspot.
But that goes against what D4dawg has experienced and had fixed.
So my plan is to approach the same specialists who fixed D4dawg's problem as it is the exact same symptoms I am experiencing on the same S54. (however mine is running the custom cams map and not the stock map). I can't see any other way out of this other than a remap.
