Comparing cars that have the same set up or "relatively same set up" may not be the best thing, especially if one of them is an AT. Different Dyno's different temps blah blah blah we all know why Dyno's are not the most accurate way to judge. Only way really know is here is the base line and here is the end result, with the same operating conditions. I hope you reach your goals but you may end up with a fast car with different numbers than mine. FYI i had my car on a Dyna Pac in Montreal and it did 265hp and 269tq BUT feels a bit less than Hack's kit. Again Different Dyno Different day and the kit is "relatively same set up"
I am just saying don't be disappointed if you do 225whp in an auto trans on a Mustang Dyno, that is still a good gain for that car considering the AT and where you get the Dyno done. Not mention the Tuner, he makes all the difference. I am still playing with my tune and making little adjustments and the car keeps getting better. What I have done in 2 months would take Hack 2 hours, thats why custom tuning costs as much as it does.

It's going to be faster than your's Brent...
I won't be disappointed if it's less horsepower for I am just excited to get this finished and am hoping out loud. It's going to be faster than it is now, one way or the other, and I'm still holding to the general rule of thumb, cc/100 (2378/100 = 238) is the maximum horsepower this stock engine should safely handle. If it produces these numbers I'll be more than happy!

yeah, UVtune is the only software out there that has the proper definitions to flash our ECU's...once you download your ROM, you open the file into UVtune and you can edit the tables, save the new file, reload new file, write to ECU...your local tuner should be able to figure it out...

" Turbochargers for Automatics
Many people wonder if it’s a good idea to put a turbocharger on a car with an automatic transmission.They’ve heard horror stories that it will mess up the transmission in no time.
A great many turbocharged performance cars have automatic transmissions in them. The old school Buick Grand National and GNX only came with automatics and they were plenty fast. Audi puts out a number of turbocharged cars with automatic transmission, and so does Porsche. In fact, many high-horsepower cars on the road today come with an automatic transmission including Jaguar, Bentley, Corvette, Infiniti, BMW, Mercedes Benz, and many others. The Bentley is particularly noteworthy because it’s 412-cubic inch turbocharged V8 slams well over 600 ft./lbs. of torque through an automatic transmission.
Many people are under the misconception that automatics are weak, when the fact is that their basic mechanical elements are strong, and in some cases, stronger than a manual transmission. Automatics use planetary gear sets instead of meshing only two gears at a time as a manual transmission does. Planetary gear sets are actually made up of six gears that are in constant contact with each other. This eliminates the need for synchronizers, and for meshing and un-meshing the gears when a shift is required. Additionally, because torque is absorbed through multiple gear contact areas, a planetary gear set can be made smaller and lighter than standard transmission gears and still maintain very high levels of strength.
The thing that kills automatic transmissions is heat. Heat is generated from a number of sources in the transmission. The multiple clutch packs (usually four clutch plates in two separate packs) in automatic transmissions generate a lot of this heat, and because they are designed to slip to provide comfortable, smooth shifts, they can wear prematurely when a lot of power is put through them. The cure for this is to install a shift kit to increase the hydraulic pressure applied to these clutches to allow them to hold more firmly and to slip less. The transmission will shift harder, and more noticeably, but will generate less heat and last longer under high power abuse. A good transmission oil cooler will also be a big help in allowing an automatic to live under abusive conditions.
One more thing in the automatic’s favor is shift speed. No matter what anybody tells you, an automatic shifts faster than any manual, no matter who is rowing the gears. Additionally, power flow is not interrupted like it is when you step on the clutch in a manual equipped car. Sure, some people can shift manuals without hitting the clutch, but those gearboxes won’t last long under all that abuse.
You may have noticed if you follow import drag racing that some teams are switching over to automatics in their mega-horsepower race cars. The reasons are pretty simple, less breakage, more tunability, and more consistent performance. Sure, manual transmissions are fun to drive, but automatics are up to performance applications with the proper preparation." - http://www.nicoclub.com/archives/tur...ans-240sx.html
