Interesting. My tuner was telling me that I should not do this when I previously understood that to be an option. Sounds like everything works well for you. Is the information to set this up available through haltech's website or on the IC-7 dashboard software?

Does yours show gear input? Like what gear you’re in?

Do you have an IC7?

@TurboTapin I am running a very similar setup to you. I have a CD009 with a Haltech 2500 and iC7. Did you ever figure out a way to get the gear input from the transmission? My r32 gtst does not have abs to pull that data from and I am using a Cusco 4.56 2 way diff not a z diff.

I will do this next week and report back but timing does not seem off.

It’s a fabbed 3in downpipe to a 3in ISR (cheap) catback. It’s all straight pipe and 1 can at the rear. I have found several examples of the same turbo making more power on less boost with 98 RON or similar (non ethanol) fuels. But, maybe I am wrong or getting bad info. 19 psi seems like a lot for that power.

I know this thread is quite old but I wanted to chime in. I currently have a rb25 neo with a g30-660 and I am getting some wonky results. I’m hoping someone smarter than myself can offer some new info. car made 373whp/300tq at 19psi on 93 octane. Tuner said the vehicle suffered from “too much back pressure” and was causing low numbers. This is peculiar considering the car is a 3” system and that should be plenty for that power level. Boost comes on exceptionally quick and the throttle feels more like an on/off switch. I feel virtually no spool. Stock Comp/stock cam rb25neo Plazmaman Plenum DBW ID1050x Haltech 2500 6boost manifold g30-660 1.01 A/R 93 octane Thoughts?
