Is it possible to run a holset on the stock computer with out a issue? I have +40, afpr front mount, wideband O2. I have the fuel psi turned way down cuz I'm only spiking 16 and hold 11-12psi.. thanks guys.

When I stab it in 2nd goes to 10.2 when spiking and 11.6 by redline.. but I mean it was really really rich when I first put injec. and afpr on and adjusted it accordingly till what I have Stated above.. so I have plenty of fuel to support the holset just not sure how its going to act on a stock computer.

I ran one with +20s just to see how it would do. Adjusted the AFPR accordingly and it seemed fine at around 12PSI. Just watch your WB and spark advance as the stock computer would run higher spark advance as say a 3bar cal.

Then keep the boost around stock levels or run alky or race gas.

Oh ok.. cuz it still can detonate even with afr richer than 11.5 right?

Yes, detonation can still happen with rich and correct mixtures.
