I own a 2009 mazdaspeed 3. I am currently running the ots stage 2 93 oct. map on my AP. My other mods include cobb sri, tih, rmm and 3" ss cbe . gfb bpv, cpe tmic, obx catless downpipe, autoxtech hpfp. I recently put on the downpipe and cbe and retuned with the AP. My problem is that while I am WOT the car seems to be bogging or sputtering. Does anyone know why this is happening?? it was running like a champ before the Dp and cbe install. Thanks fellas! My only thought would be that the AP stage 2 map is for the cobb catted downpipe only, while I am running the obx catless. Is this my problem?
