Here are the first 3 pulls at operating temp after the flash to the E30 map. Interested in your thoughts because my butt dyno didn't register much. Car felt like stock at 50% throttle from stoplight to stoplight when getting up to operating temp and WOT pulls weren't anything write home about.
Do the MHD OTS maps learn/adapt over time? Do I need to do some additional pulls to see additional gains?

Edit: Technically SC_B5X did reply to one of my earlier posts with a recommendation to purchase the wifi adapter instead and my dumbass didn't see it before I bought the cable.
Generally it looks like a Stage 2 MHD E30 log for boost, timing and AFR. The only thing that looks a bit off is rail pressure. Mine on that map actual was flatline following target. Maybe try reset adaptions from the Codes menu?

Do you have draggy?
