I have researched my brains out and I am am putting in a K&N drop in filter and getting a tune. I think I am going to get the tuner/tune from americanmuscle.com and getting the tune from Bama. Has anyone had problems with them or will thins work. I figure you get free tunes for life and I always have the option of getting a tune from someone else once I have the SCT SF3 tuner. Any advice? Thanks

Expect only 1-3 hp from the drop in only.
I've dynoed tested the K&N drop in's on a few cars and that's pretty much what I've seen.
In my experience, only the 2.5 T F4 in the Subaru's need a tune with even the drop in filter. Their AFR's are on the "critical" side of things that even adding a bit more air from a drop in can lean them out too much.
If you want more realistic and usable gains, you need a full CAI system.
Sorry can't help on tunes for the Mustang, haven't ventured their yet.

Good luck

Chris Rose at Tillman strongly recommended that I avoid "drop in" filters like this when running a tune. Logic here, both the drop-ins and the tune (when written for the stock intake and filter) lean up the air/fuel, and you could perhaps lean it out too much. There was also a tendency for owners to use too much oil on the K&Ns, and that oil would end up in the intake.

You're better off using a CAI that requires a tune, and then having the tune written for it.

I just don't feel like spending $600 to $700 on the CAI/Tune combo right now. I keep reading that the tune gets you the most gain on our 2010 Mustangs anyway. I wanted to get some Flowmasters instead of the CAI. I figured with just the tuner I can get some gain now and add stuff to it later. I just want to get the best tuner and a tune from the best people.......Bama or brenspeed or whoever.

Yea, you're right -- the tune alone is the best bang for the buck. But, if you don't want the CAI, I just wouldn't waste your $ on the K&N either.

Brenspeed Tunes are awesome I have them on my 10 GT cannot wait till they start writing new ones for the 5.0

How much are the tunes on the GT?
How much power do they get the 4.6 liter?

I installed my K&N drop in and took it for a spin. I know the car really well and I can't say I gained a bunch of Horse Power but I did feel better response from the throttle. I am positive it is not just in my head either. I think adding the higher flowing filter to the improved 2010 GT's intake allowed the engine to breathe in a lot better. I now am ready to move on to a tune from either Bama or Brenspeed......probably flowmaster american thunder classics first......Let the modding continue..

did you go from 87 octane to 93 and feel the difference too?

sorry.. but i can't feel the difference in 10whp..i'm surprised you felt anything with a drop in.

Like I said, I don't think that I feel More HorsePower....More throttle response......for $50 I think it was easy and cheap. I think a tune will compliment the system.
