Boondocker duty cycle issues

[Hangtime]

Just installed the auxliary injectors in a Boondocker pump gas unit. Installed the fuel pump booster , changed all fuel L & H settings and fuel RPM settings .. Duty cycle is still at 99% ... Temps are pretty normal on EGT 's. very sluggish out of bottom end .. Live in mn , main reason I did the extra injectors was because of my elevation and maxed out duty cycles at 7 pounds boost ..

Thanks for any help you can give ....

What is your CR number?
That is what turns on your secondary injectors.
on a pump gas kit, it is set to something like 99 (doesn't turn on )
The CR number is 4.5 x psi, so if you want the secondaries to start coming on at 6psi, you would set it at 27.

If you are getting a sputter as they turn on, check your OS setting. I think the factory setting is 20. Mine transitions better if I have it set around 15.

then you can play with fueling settings for days until you get it dialed in.

Duty cycles

The Super tuner said CR21 , I ended up at CR15 .. Then adjusted the box from there ... works well now ... Boost on !

If we have any flat landers that need box numbers let me know ...
