2g timing map ok to use for testing on a GVR-4?

[4gfun]

As you probably know, I have a boost fade problem and want to see if I could use a 2g timing map in my 91 GVR4 since it has a less agressive timing curve.

I plan to run 22 psi at 10.8 AFR for a short period of time. If so, which load tables and RPM tables (I think that is what they are called) should be modified?

The upper ones? I am not trying to tune using this method just see if the boost fade goes away.

I am using RT Tuner PRO with Ostrich

Thanks!

Worked just fine FYI.
