do 550cc injectors run smoother?
Do 550cc injectors make the M113K engine run smoother, or did I have issues with stock injectors?
Old stock injectors were less than 30K mile/ 2 years old, replaced after one of the factory ones got stuck open, and hydrolocked the engine
Yet, the car is noticeably smoother with 550cc injectors, when you go first step on the gas pedal, from any speed, and most pronounced when you shift to D, let go brakes, and first touch gas to move forward, for a fraction of a second, when engine speed starts climbing from 650, to whatever you open the throttle to, that little "buck", or "engine fart", when you go from idle speed, to running speed, is gone,,,
I am just curious if anyone else noticed such phenomenon, and its the new injectors, the tune, or the old injectors?
PS. The buck I describe is was not really an issue, and would mainly go unnoticeable for most drivers, it wasn't a defect, and was fine... its just that the 550cc injectors made smooth smoother...

If your car is running smoother now means your old injectors were dirty.
That buck is your clutch pulley and fuel mapping on tip in. on your tune.

I ll rule it out as crap injectors, as I bought those off eBay two years ago, when one of the factory ones got stuck open. They were Bosch, but I always questioned their authenticity and quality, due to price

Nah, I am talking about engine hesitation for a fraction of a second, not the much more pronounced clutch engagement surge, that one is actually even more pronounced now... but it doesn't bother me...

I've posted this years ago -- while they are very expensive, the 6 port SLR injectors are superior to all the rest. It's the spray pattern and better atomization that make all the difference.

They are plug and play, no pigtails needed.

Edit: Chatting w/ M3diesel who helped develop the kit "The adapters that they include will cause you to have to clock the injectors and makes the OEM clips, that hold the injector to the fuel rail, useless. The adapter that have 2-3" of wire between the EV1 and EV6 are the necessary adapters.."

Sadly, I do not. Also, to clarify the kit includes a set of EV1 to EV6 adapters under their kit part number.
