www.steeda.com The actual site isn't linkable through that site (just brings you to the homepage) but if u wanna check it out its on there. Its 400 bucks and i have a manual 02 GT. They claim 20-30 hp in the cobra. Woudl i really see any increase in my GT. Theres no shift points to recal since its a manual... But i might be getting gears soon so it would be nice to recal the speedo. It says

DiabloSport Performance tunes require the use of Super Unleaded/ Premium grade fuel only, Amoco, Sunoco or Mobil if possible.

I really dont know about any of that stuff... i dont know about any of this. If i make a mistake could i go back to a "default"? Also, would you think there is like a preset tune for like premium fuel, since the mustang is already optimized for regular premium wouldn't do much but witha recal it might??? sorry guys lot of questions lol but i dont know much about this.

 

if you go here you can get it for $50 bucks cheeper http://www.partshopper.com

 

look on ebay i think they have them for cheaper than both of those...

 

here is one for 309.00+15.00 shipping... Not too bad...

I just bought mine and installed the HP tune. Love it. More power. Be careful. Don't crank your timing too high and don't ever go too lean. If you don't know much about it yet and don't have access to a pro and a dyno, just use the latest diablo tune for now and hope to gain 10 HP.

I bought mine new from e-Bay. Use a dealer who has thousands of happy customers. Watch the shipping. Enjoy!

 

What would the best tune for me to do on my car. I have the Predator and right now I have the torque mod all the way up and adjusted the A/F when 2-4k to 3 lean and 4-7k to 4 lean.

 

Advance the timing all the way for best performance, that is safe, I have done it on my Gt and many other friends at the dragstrip- the difference is really great but run 93 octane. Dont mess with your a/fuel without being on a dyno you are playing roulette there.
