Broke down and bought the Hypertech Sport. Going to install it tomorrow morning. Can't wait to feel the difference!!!
New Hypertech

I'm wondering if, with your exhaust side mods, you would have been better off with the AP and a custom tune
I'm not saying you won't feel any difference (remove the low gear limiter and you will), but the HT might not give you what you could get with exhaust setup

this will be an interesting one indeed.
In theory it should cover it since the turbo is stock,
I would be very interested in seeing a dashhawk graph 4rth gear pull from 40 to 80 after the tune has settled in

get a before and after dyno
With OP's mods, such a fourth gear pull graph might look something like this posted below:
Almost no "peak" power gains at 5,500 rpm at this mod level (actually peak is about 11 hp higher, but it occurs earlier) as the engine is closing in on load cap, but huge increases in torque and a much broader, flatter power curve that is much more usable before peak power and an nice extension of usable power out several hundred rpm higher than stock tune.

kickass, thanks. is that with all mods in your sig?

Yes, the red line and the higher dotted torque curve are with all mods in the signature.
The black line and the lower dotted line represent all mods in signature but before adding the HT tune. Do not take the hp and torque numbers literally as absolute numbers, but rather look at the differences between the before and after numbers.
And also realize that as rpm increases in those 4th gear pulls, this is out on the highway and not strapped down to a dyno, so the hp is actually pulled down by the effect of aerodynamic drag which is damn severe by the time you get to high rpm. You are actually losing 40-50 whp to drag by the time you get to 5,800 rpm, so keep that in mind. Whp out there is probably in the 280-290 range as it might appear on a chassis dyno, but that is just an estimate.

I just got my hypertech in the mail today. Any thing I should know that is not in the instructions? Any tips? MSCAI is my only mod.
Thanks for the help.

Its so simple if there were mazdaspeed3's during the reign of cavemen, they could have done it
But really, plug it in, do what it says. With mine it told me I had to update it first, so you might have to do the same. Don't bother until you hook it up to your car first, cuz that's when it will prompt you to do so
It will automatically ask you for things like intakes, or 0-60 restriction, redline limit, etc. Everything is done from the drivers seat
And as for break-in period, chris@hypertech has explained that there is no need to, so don't feel like you have to baby it for 100 miles
Just realize if you take off the restriction in 1st and 2nd its realllllly gonna make your tires spin like crazy if you gun it

Thanks a lot.
Eh, I need new tires anyway.

Just installed this baby and I am liking it!! Feels so smooth, like everyone says. Power is there when you want it and shifts so easily. I have had the Cobb AP so now I am able to make the comparison of the two and I choose the Hypertech. So much smoother and well rounded power than the AP. Yeah, there is definitely more boost with the AP but nothing about that is smooth. Car jerked like like a seizure with the AP.
Plenty enough early power and torque for me with the HT.
I'm sold. Completely.
When I get my CP-E MM installed, I'll be a happy man.

Yea...a motormount is something I keep putting off that I know I should get

Oh so true
Assuming a more-or-less constant drag coefficient, drag will vary as the square of velocity. Thus, the resultant power needed to overcome this drag will vary as the cube of velocity. The standard equation for drag is one half the coefficient of drag multiplied by the fluid mass density, the cross sectional area of the specified item, and the square of the velocity.
For giggles, take a 4x4 piece of Luan and staple the straps from an old backpack to it. Hop on your trusty ten speed and start pedaling.
you will get a much better idea of how important drag is.
Not meaning to jack the thread, but calculating the loss due to drag is pretty easy if someone makes the calculator and puts it online:

BTW: The MS3 has a drag coefficient of .32 and frontal area is 25.5 square feet, according to Mazda.
