If you have a test pipe to replace the 2nd catalytic converter, you'd be best off running a stage 2 map. Either way, I would probably start with a Stage 1 93 +SF or Stage 2 93 +SF depending on test pipe and octane available.
Thanks man. Installed Stage1+SF 93 today.
Does anyone know if the mzdspd.com website still gets updated? All of the maps there were v102 or v103 but all the stuff on Cobb was v104...
