I'm looking for some feedback / input on Arizona Speeds
Throttlebody, ECU & Flame Arrestor package claiming an increase of 25 hp for approx $1000. I'm considering adding it to my 525 EFI. Worth it or not? Cheap horsepower for the the dollar but is there any noticeable difference in fuel mileage, throttle response or top end? All responses welcome. Can anyone suggest a better way to spend $1k for performance goodies?
Also looking for the pros & cons of CMI's switchable exhaust vs mufflers. How many Pantera EFI owners opted for it vs those that passed & why?
