Default Overboost Adjustments w/ logs - 04-25-2022, 10:03 AM

Having some issues with the boost struggling to stay on target. FF seems to be consistently higher than the WGDC so my though would be to lower the Duty Cycle for each RPM range or reduce the FF under the Adjustable Setting's since it seems to be lowering on its own after each run anyway.

- Pure Stage 2 Hi-Flow Twin Turbos with 2" inlet
- High Flow Relocation 2" Inlets
- JB4 with MHD back-end flash
- ER Charge Pipe & Tial BOV
- Custom Intake and Air box
- RB PCV Valve
- AR ******* *********
- N55 Midpipe
- Berks Race Axle Back
- Improved Racing High-Flow 185F External Thermostat
- NGK 97506 2-Step Colder Spark Plugs

3.5 Bar TMPA sensor on order, but stock TMAP still installed.

The first log seems ok, but the second run after shifting to 4th, it seems like there is a struggle to adjust the boost and it kicks me into Map4.

Raise your boost safety to 23 psi. Scale down your duty bias by 4 in all boxes. Trim variance is also existent, not bad, but if you have no record of replacing O2's or if you run burbles frequently, make sure to check them. It also wouldn't hurt to check if you have a clogged/leaky injector.

Hey Cannon, quick question.
I thought Terry said the boost safety is basically not active anymore ??
It triggers a few psi over target regardless of what value a user enters ???

What are you using on the LPFP side?

Your Psi is tanking towards the end of your pulls

Still stock fueling. Ultimately I'd like to be in 600HP territory so looking at Stage2/Stage 3 LPFP options. Still undecided on PI vs HPFP overdrive.
