Holy mother of large type Batman!

Welcome to the forum tuning will give you a ~35hp boost over stock. Go to the track and tell us what you ran before/after the tune!

there's not much chance that you will drop a full second, that would be like a 100hp gain but maybe drop .3 seconds just tuning alone.

dual tune is where the tuner tunes both octane tables(high/low).for example 87/89 tune or 89/91 or 89/93.id just stick with the highest octane.there's not much gain from an 87 tune IMO.
