I would like to upgrade to a performance chip but I run the ROW maps which run smoother on my car and want to be able to run those maps(without closed loop with the O2 sensor) but still have the benefits of a performance chip to be able to run 15psi with reliaboost as the controller.
Does anyone do this?
Thanks

I would guess my 951 ran on ROW maps originally... later on it was equipped with a set of SuperChips, seemed to work fine, and now I have the Gurus in there.

You want to run without your O2 sensor? I'm guessing you had stumbling problems? Is this your only solution?

Without restating another post...I have been through everything and still mild part throttle stumbles. Yesterday I pulled the intake and replaced everything else to no avail. Stumbles on USA map...you can watch the AFM dithering during accel like its in closed loop...as soon as it drops to open loop, it smooths right out. ROW maps run just fine as its in open loop all the time.
