Tune questions for 05 v6 mustang w/ bbk cai

[holowach]

I bought a used diablo sport predator (U7140) for my 05 v6 mustang, i just installed it with the 87 octane performance tune. the guy before had a custom for his C&L cai which is still
on there. Can i just change the Global MAF thing by 5% in the 87 octane tune ? I have a BBK CAI, Airaid Throttle Body Spacer and a single axle back borla exhaust. Any tips on
what i should do, or should i just keep it running the regular 87 octane performance tune?

no, -5* of global spark.
