Since I got my Kraftwerks kit put on, Ive noticed kind of a bad bog/hesitation around 2800 rpm. I informed Vit who is doing the etuning, and was told that it was a mechanical issue, i.e injectors, clips, plugs, coils. I quickly ordered and had instaled new injectors, upgraded to ID 1050x units, after hearing what Vit thinks about Grams injectors, NGK 1422 plugs ( i believe thats the number, one range colder ), and took the car back to the shop that has done all the work. They installed the injectors and plugs, and tested all fueling and ignition components. Thought I was good. Well, Ive continued tuning, and everytime at about 2800 rpm, in any gear, it stumbles terribly. I pulled up my datalogs and took a look, and every datalog has the same injector spike as shown in the photos below.It only ever happens in that exact same spot in the datalogs, nowhere else. I brought this up again in my note to Vit with last nights datalog. Waiting to hear back, but was wondering if anyone has any input in the meantime about what might be causing this other than a tuning issue. Please forgive my ignorance, and much thanks!!!
