Green top injector questions

[Mediumrarechicken]

For those that swapped the green tops on to your m20, how much better did your mpg? And for the guys that dyno'd it afterwards did you see a hp increase?

Anyone?

[Kershaw]

No and no.

[MrBurgundy]

No and I've never dynoed my car.

I haven't dyno'd but it feels good to have them. Likely more related to having clean injectors than anything else.
Best part is that it gets rid of the super loud tick of the stock M20 injectors.

Waiting to get a MarkD board done for them to take full advantage.

Yes and yes, but you got to use 2.5 bar fuel pressure regulator. smoother idle and better mpg
