I have a 2005 Mustang GT:
Aftermarket i have:
SLP loudmouths (in the mail)
K&N Air filter (not the intake)

Factory:
Fully loaded, minus red insert seats.
IUP, Auto Tranny, Leather, Mycolor, etc etc etc etc

Im getting a few hundred for my birthday, and i have some more money saved up.

I was wondering a few things.

1. What would be the best PERFORMANCE mods to get. I dont have funds for Blowers, and i dont want to install anything too crazy or hard to work on.
2. If you said a performance chip, How would i go about getting the right tunes, etc.
3. I found a n2 kit for the 05 gt, and i was wondering why more people dont have this. it seems around 500$ and claims adjustible HP gains from 75-150. So if 500$ can even get 75HP safe on the stock motor, then why havent i seen anyone on here with it?
4. This will sound dumb, but whats a good gear ratio to get for high acceleration... or would my 3.31 be fine? (4.10 2.73 etc)

 

I would suggest a cold air kit and a tuning kit. Often you can find tuners who make custom tunes for specific cold air systems, which makes picking the system all the more easier.

Cheak www.rpmoutlet.com for an example of what I'm talking about. Their C&L cold air intake comes with a Pred tuner with a specific tune for the kit.

 

thanks!!

 

stay away from the Nitrous... if you are upgrading a step at a time, that is step 20 and you are on step 1... CAI and a Pred or SCT are what you want...

 

alright.

anyone agree SCT is the best?

 

I prefer Predator, but there really isn't a difference. It would be better to decide on the two depending on what a local dyno tuner has experience with. For example, I found a tuner about 2 hours away from me that works almost exclusively on Predator. He's done SCT tunes, but he specializes in Predator, so I got a Predator.

I would call a few local shops and see what they specialize in. Predator does have a few options that SCT doesn't, but that won't last for long.

 

Thats like debating different computer manufacturers... no real difference...

I have the Pred and I like it alot. It is very easy to use and simple in operation... and the support from Diablosport has been first rate.
