Pondering some things while I should be working. I have a 98 V70 GLT with stock 13g turbo for now. I'm having an OBX downpipe with 3" components (cat, resonator, dynomax ultraflo) installed Thurs. So not having turbo maps in front of me, if one was to want good off the line quickness (0-60) versus strong top end (40-100) would I be better off getting an ARD orange tune for my 13g with downpipe (12psi), or 15g with T5 ecu?
