I'm not sure about Doug or Brenspeed, but I do know that Lidio from Alternative Auto has a stock airbox tune which claims is good for an additional 20 HP. Anyway ? hope that helps out.

15-20Hp is the normal realm for them. The Superchips setup is good for 15Hp on 91 Octane in a 2005, and the others are all similar. Best bang for the buck out there, IMHO. Plus, with most of them, it gives you capabilities to change other things down the road that you couldn't without it - ie. gear ratio reset for the speedometer, OBDII scanning, etc..

If it seems that 20 HP is a bit much for just a stock airbox tune ?? then ask Lidio from Alternative Auto and find out for yourself..here's the website www.alternativeauto.com

They say they gained 4-5 HP removing the hydrotrap which only the earliest cars had.
They say they also gained HP from changing to a 93 octane tune instead of 87.
Do the math, they are actually getting less than 13 HP.

Well, I don't want this to turn into anything other than a rational discussion, but the 15Hp on 91 octane I'm quoting is off of our car, which at the time was 100% stock - INCLUDING the hydrotrap. So if you push up to 93 octane, pull the trap, and get things just right, I'm guessing you could pull 20Hp - of course YMMV. The dyno runs are attached, and the Superchips dyno at the main facility is notoriously on the low side.

Well, Like I said, that was 100% stock - also, the graph is running up to 6700 RPM, and the lines do cross at 5252 (approx) as they should. If the graph were "trimmed" to 6k, the drop-off would be less noticeable as it really starts to drop above 6k. I haven't looked at too many stock plots in that RPM range to compare to though, so I could be a little off on this.

Why not just get a CAI too and maximize the potential of the tuner? They can easily be replaced with stock airbox before any dealer work? Not trying to say you shouldn't just get the tuner but the tuner and CAI together really wake the car up. You would enjoy!! You know you would!

BTW, the two CAI that I favor most are steeda and JLT (I believe in a plastic intake tube). But I can't say yet which one I'll choose.
If a tuner alone can give 15 to 20hp improvement, then I think we can all agree its one of the best "bang for the buck" mods.

By removing the “Pre-Cat”, switching to “premium fuel”, and implementing a well-thought-out computer tune/flash we gained 20 RWHP and substantially better throttle response. The new flash can be felt immediately, even under light to moderate throttle conditions. .Now where do you get 13 HP. from ?? look the bottom line is if your expecting to gain 20 or more HP from running 87 octane ? then no of course not..in fact you won't even see 20 HP with both a tune and CAI combined if you plan on running 87 octane.. any tuner will confirm that an 87 octane tune just isn't that aggressive compared to 91 or 93 octane tune..But what do I know ?? I never claimed to be an expert on tuning ? I just stated what was claimed, therefore if you wish to dispute the claim in question ? then you need to take it up with the source..

Originally quoted from Alternative Auto...The base line pulls from the car averaged 265 RWHP and 276 ft lbs of Torque.

don't waste your money! If you buy a tuner for your stock box, you will then need a new tune for the CAI. You could pick up a used cai in the FS section for cheap and then if you don't like it your not into it for a lot of cash.
JLT/Xcal 2 combo is the best bang for your money (from either source you mentioned), although I am a Brenspeed customer.

Karman ? again your asking the wrong person to do the math..And not to sound like a wisea$$ or anything but ? I didn't create the tune nor am I a tuner ? so why should I care as to whether or not his 20HP claim is accurate or not ?? as I previously stated ? if you or anyone else happens to dispute his stock airbox tune results or whatever he calls it ? Then ask Alternative Auto to re-do the math..

Okay, just like with my own kids (adults) I'll do the math.
Final Number:............. 285 HP
Removing hydro trap:..... -5 HP (only in the early '05 Mustangs)
Changing to 93 octane:.. -2 HP ( with 93 octane"we got more aggressive with the timing")
Actual gain:........................278 HP ( 13 hp over 265 stock)
I agree with their claims 100%
Do you understand what I am trying to say? I'm just going by what they are saying.

After you broke everything down ? yes I get it now..I misunderstood where you were coming from and took the 5HP for the HC trap and the 2HP for changing over to 93 octane as reducing power instead of increasing it..hell one the first mods I did to my Stang was yank that power robbing piece of crap out of there..
