Stock Injectors or replacement

Yikes. That's worse than mine!

Sounds like the ~2800 RPM jerking that the MS45 cars get. Try flashing it to the latest software, that fixed it on my old ZHP.

Not a typical DIY, correct?

correct me if I'm wrong but the "jerking" your referring to at 2800 rpm is a dip in the power band? this is not the case, this a literal sputter of the car, like its misfiring. dealer told me its 150 for the flash but they don't wanna do it.

-Update- drove to work today. on the way there had my DISA disconnected.- no dice. on the way home, disconnected the mass airflow sensor. this appeared to have fixed the problem. I got home and cleaned my MAS with contact cleaner. the commute tomorrow will let me know if i fixed it

Interesting. Sorry it didn't work. BP will school you on not cleaning the MAS (though I've done mine).

worst comes to worst i guess ill just replace the thing if i damaged it, cant be more then a couple hundred

I don't think its instantly ruined. Mine seems fine. Others here have done the same.

No, it very much felt like a misfire, except it didn't throw codes. I remember it being most pronounced in 3rd gear.

Can be done with WinKFP.
