Deleted SAI, N112, o2 s2 sensor and added overrun.

The car goes ok but feels a little hunger. What else could I change to improve performance in the program?
My MAF is old (F00c262040 487121c) and calibrated in program.
Mod in attachment. Anyone help?

The question should be what to Log and then adapt to have a better tune...

It helps spool. I've never had one break.

That said, we need logs.  What have you changed and why?

I actually do not know what else to change because the top turbo does not hold you very much... I do not know if the maf flow underestimates or turbo is weak.
