On the street I have seen 43psi or so running a DTS 69/74 IHI running 100% over injectors and 10mm pump. Didn't pay attention on the track but will this weekend as I've got a pull Friday and Saturday night.

I am running 100s with a 12mm pump. Thinking maybe to much fuel for my now 69/74 ihi. Possible that a smaller injector will allow me to run a bigger pulse width which should help drive the turbo harder.
