Question about injectors for enthalpy tune?

[kpc_0721]

Just curious if anyone knows if I could use the Ams precision injectors with a enthalpy ecu tune....it says on the website that they can tune for #50 and #72 MSD top feed injectors so would that be a no then? One more question kinda off the topic but I will running 12psi daily driving and high boost setting will be about 20psi, maybe 22psi but would 780cc injectors be to much for that amount of boost?

I always like to use huge injectors given the opportunity. Since I often run more boost then I initially plan. As far as the ecu tune goes, just buy the injectors that the tune is meant for. 72lb injectors will let you run more boost then you'll have tire for anyway.

so 780cc's wouldnt be overkill and with enthalpy tunes you can really only run the amounts of boost that I tell him as in low would be 12psi and high would be 22psi and he tunes to those amounts of boost and my setup pretty much? Thats how I was told how enthalpy tunes work but so would running more boost then planned with enthalpy tune be bad? Sorry if I am making this sound confusing but I am trying to explain as best I can....also not really sure what 72# would be in cc's?

You'll be fine with hsi tune. Let him know what you'll be doing. Also let him know your octane there if it is 93 or 92/92I've run 8psi with 555 injectors then cranked her up to 19-21psi with 0 problems Well except for traction

72#=755cc on 4cylInfo can be found in the sticky at the top of the thread zerothread?id=109492
