Hx40 swapped need info on better injectors

[couleebasinfireservices]

Looking for better injectors to throw at this ldt465-1-d . Willing to sacrifice the multifuel capabilities on this fire engine to provide better power. Currently it runs around 890degress wot in 5th with a full tank of 1000gallons on 6% grade Ive been testing on .weight of 22900lbs+/- . I know I still have room to add fuel at the current egts but would like to move to a more modern injector or injection system. Does anyone have anything to recommend?

1987 m35a2
Ldt465-1-d
Hx40 swapped
11psi
660cfm filter
New external filter canister (haven't had pics yet)
4in intake tube

I don't think there is an injector upgrade for that engine, if I'm remembering correctly, that already has the LDS patterned injectors on it being a late model 1D. You can build that engine into an LDS, or swap to a Cummins, but as it sits, your option is turn the fuel up and keep it below 1200 degrees. White Owl Parts has new injectors, they would probably know better than anyone. Hope it helps.

Fantastic build btw, love the look.

Well that's not what I wanted to hear but thanks for the response. This truck sees long grades at full weight and already performs much better but I had been hoping to really wake it up reliably even if that meant sacrifices

Here are the pictures of the air intake filter canister we built in house to complement the hx40
