20+ injectors too much?

[mopower76]

Hey all, I believe I jumped the gun and bought a set of MP 20+ injectors.
I don't want to over fuel and wash down the motor, but I do want more fuel for
the higher boost levels.

90 Voyager Turbo
T2 Garrett
FMIC
BOV
grainger valve
3" down and electronic cutout
255 pump
Stock injectors

will a FPR help or can I do without?
Thanks!

Also Zener Dioed on map sensor

No, I think you probably need them with that set-up. I would suggest a wideband O2 and adjustable fuel pressure regulator to help fine tune the fuel

Thanks! I am trying to buy a wideband AF gauge now actually.
trying to find a good (cheep) used one.
Im a bit relieved to hear I didn't waste a lot of money on the injectors.

My personal experience with wideband o2 sensors, as well as the dyno shop I like to test my car at, find wideband o2 sensors give up after about 3 years. Save yourself the money in the long run and buy a new one to avoid getting someone else's problem. It's worth the money to not have to change pistons regularly, or worse.

Ok, that's good advise. What kind of FPR should I be looking for? Does it need to be for fuel injection or does the gauge just need to read high pressures? What kind of pressure should I expect at the guage?

i wouldnt bother with the adjustable FPR.

id spend that money on a chip burner and chips. Moates Burn2 or one of the MCUMall.com USB ones.

then get a socketed ecu or socket it yourself if you have soldering skills.

then make your own chip that can support +20 injectors and turn the boost up some

Or a flashable computer.
If you are going to keep making improvements, it would be better to start into the tuning learning curve now, while you will just slightly tweak stock tables.

Yup flashable computer from boost button would make things simple.
