hey man, Almost everything you want to do to your 8 for cheap will get you some power but when is comes to modding nothing is really cheap.. To get a lot of power out of it will cost a lot of money. The only way to get a lot of power out of our cars is FI.

setting your redline higher wont make more power on its own. the cars power curve starts to fall somewhere between 8500-9000rpms in stock trim iirc. and around 7500rpm in most boosted applications....
you can make more power while raising the redline, but it will require more complicated work than just raising the redline with a flash tune.

you should get it, for a slew of other reasons.
Oiling, cooling, MPG, and in combination with some of the other popular bolt ons you can get a few extra horses out of it - just dont expect miracles.
i forgot the AT is limited at like 7500 or something right? so increasing the redline to 9000 may give you a bit more power, im not sure. either way i know power starts to drop off well before 9000 so no sense in ever going beyond that w.o significant other mods.

FI = forced induction (turbo)
AP = AccessPort
EMS = Engine Management System
As far as learning more about the AP, check out the MazdaManiac AP threads. If you buy one, I highly recommend going through him.

FI is more than just a turbo... FI stands for Forced Induction such as Turbo, SuperCharger, and Nitrous

Before you go forced induction. I have a Borla Exhaust on mine and its doing not much.
Start with the complete exhaust system (headers,catback, etc..) then you can move on and get other various parts for some small HP gains (Intake, Ignition, Stickers..etc..) the Best HP gain would be a FI system such as the Petit Supercharger kit or the Greddy Turbo kit..
The MT 8's also have more power..

There are two ways to get better performance out of your 8 from a speed perspective. You can either increase to power output of the engine or you can reduce the weight of the car.
For increasing power I would suggest starting with a 3" intake and exhaust. They are low cost in comparison to most of the other mods and are not too tough to install. A CAI (Cold Air Intake) is best but a bit more work to install as you have to remove the front bumper to put it in.
After a CAI and Exhauts I would look at a high flow midpipe. And maybe the AP (Cobb Access Port - talk to MazdaManiac). Better coils will help (talk to Charles R. Hill from BHR) as well.
The basic goal of engine performance is to move more air through the engine. As MM has said many times, horsepower is generated by more air moving though the engine. FI (Turbo, SC, Nitros) just pushes more air (and fuel) through the engine making more HP.
For reducing weight, look at simple things like lighter rims, custome seats, carbon fiber body parts (although the CF hoods tend to weigh just as much I think), etc. Every 10 pounds you loose on the car weight is about equivalent to adding 1 HP.

If you change the intake/exhaust/ignition/ and midpipe, you will need to do some tuning of your 8... So plan on doing at the same time... Cause once you do all these mods at the same time, you will need to tune... Take from experience...
Happy mods.... Brannon

hey why would I have to tune it once I do the intake/ exhaust/ignition. Why would I have to get it tuned..!???? Tag sosent make no sense, unless the parts will effect certain things. Please let me know what everyone thinks. Thanks

You will get more out of it when you have your 8 tuned. What Im doing so I dont have to retune is get all or most of the parts on and then tune. Im doing the Full exhaust (header, midpipe and cat back), Pulleys, Full intake, and Nitrous. After all that I will get a lot more power out of it.
