I have a 2000 Mustang GT and recently purchased a u7146 Predator and was wondering if there is an 87 octane program or do I have to use the 92 octane.I have a full tank of 87 and do limited driving so it will take awhile to use up but I would like to install the Predator. Should I just run out the gas and program it for 92 octane? The GT also has a catback and an aftermarket larger Granatelli MAF. Should these be taken in to consideration when programming?

Thank you

That MAF may cause issues, but there is an 87 tune in the latest revisions.
