mods: cfm tb, steeda cai, magnaflow catback. no more planned upgrades. 151k original owner (me) miles on the ticker. I recently switched to M1 5w30. long commute, 65 miles each way, primarily highway. what "gains" would I be looking at with a tune? I know the tranny is null. also, I do not own a laptop or tablet, so data logging would be out. I work in parts at a ford dealership, so I can run my vin and get you the pcm code. can you do a good canned tune, or do you need to tap in? just wondering if it's worth putting $400 into this thing at this point. thanks.
