Re: hesitation

Did you add any kind of fuel controller? I noticed a flat spot not hesitation when it was in stock skin after removing the stock cat for a dual M4 I didn't have a hesitation but it id run a little lean. I would add a fuel controller of some kind being as though you removed the cat.

Re: hesitation

Did it happen exactly after you made all of the changes? Or develop over time after the changes?

Check the fuel pump and then the EXCV. Odds are high that it's one of them
