quick question about tunes

Hi guys, i know this question has been probably asked a million times, but what kind of HP gains would I expect to see with the ford racing cai and tune for 87 or 89 octane fuel., 10 to 15 perhaps ? Not referring here to actaully putting the car on a dyno and tuning it, but just one of the tunes offered with the sct tuner from American Muscle.

You are close. Each otane boost is approx 4HP more. The Ford racing setup is a little more conservative than say the JLT CAI and tune.
You can get up to approx 20-24HP on 93.

is there any real benefit to getting a CAI at all then? Or will just the sct tuner suffice?

your power gains are greatly increased with a CAI & tune vs. a tuner alone.

2008 Mustang GT Premium 5 speed, MGW short throw shifter, 3.55 gears, black-on-black, IUP, 18in polished aluminum wheels, FRPP GTA Axle Backs, JLT II CAI w/SCT X-Cal 2. 296HP & 311TQ

Also remember that when you have a tune built for you, you can also have many customs features tweaked at the same time. Features like having the throttle close down quicker (more like the way a normal car feels) to get rid of that annoying throttle lag on deceleration, and if you have an auto, you can have your shift points and firmness altered. Be sure that your tuner is aware of all the mods you have done and also mention to him the things that bugg you about the way your car drives. Chances are he will be able to tailor a tune to make the car drive exactly the way you like. The difference can be quite startling.

sorry for not being clear, I was referring to a base SCT tune from BAMA tunes that you get when your order a CAI and SCT tuner from American Muscle.

It depends on what your objectives are. If you just want a little more power, responsiveness, (and if auto, quicker shifts) then just the tuner is fine. But, if having 25 extra HP along with all of the above is what you want then get the CAI and tuner combo.

Personally, I would get the combo and get a 91 tune along with an 87 tune. If cost of gas is a concern, run the 87 and then when you want to have some more fun put a tank of 91 in and change the tune.

Ditto. Even if you didn't see more horsepower, the improvement in the throttle is worth the price of the tuner. Add in all the other things that you can control and improve, you'll quickly understand.
