Just want to make sure something else isn't wrong with my car

Single turbo
850/1680
Base map with the injectors changed to proper size (1500 for secondaries) and 64.5% and 51% respectively. O2 disabled and sequential disabled

Car isn't great at idle but good enough. Concern is when the car sees any boost, anything greater than 0, it falls on it's face. Not running it hard at all just enough throttle to see any boost causes it.
If I disconnect the elbow it has no issue so it's definitely something to do with the computer seeing positive pressure.
So I just want to make sure that this is most likely a tuning issue and nothing to worry about?

 

850 primaries is a big mistake today with the ID 725 available as 850 are too hard to properly tune except using negative lag.

Even the stock 550s with ID2000 secondaries are good enough for over 450whp.

Bosch 1600/1680 require a resistor inline with the PFC due to their low impedance.
Use a low impedance drive for them and they will run like larger injectors.

Was originally made/sold by AEM but now under Holley control.

Most likely your map has bad settings, or engine setup is bad.
Like map sensor connections and setup.
Attach map.

 

It's the base map from the apexi. Resistors are in place and vacuum lines look good. Used to keep the seq twins working so pretty confident in the hoses. Hoping it's just the map. I know changing the lag certainly affects how it runs. Seems best at 0 for just driving around

Thanks for responding. If I keep the rotory I'll need a datalogit, started doing track days and engine went due to wastegate vacuum hose popping off and over boosting at wot. Even though it was zip tied, need a better solution for that.

 

The trick to lean out 850 as primaries for idle, is to determine how much the negative lag reduces duty cycle.
If with 0 lag it runs too rich; then record idle duty cycle, adjust to negative lag to get proper idle and decent AFR,
record new duty cycle, calculate % change in duty cycle that it took to get leaner and smoother.

Thus if it went from 5% DC to 4.5% DC, 4.5/5 = .9. This is making the injectors run like .9 * 850 = 765cc.
Enter this for the injector size and used to determine ratio of old primary to new primary. Then retune fuel again if needed.
