So drove in normal (not for long). Amazing.... for $180.00 and plug and play. Don't knock it until you try it. Way beyond my expectations.
SBCY00036? You are definitely got the wrong device. Manufacture 's part number is
SBCY0023S on Jegs website for Chrysler Crossfire.
$180?
Thus, a product that normally costs $289 with a 20 percent discount will cost you $231.20, and you saved $57.80. Plus TAX.
Enjoy your Sprint Booster

This is absolutely not necessary modification. The German engineers designed acceleration system to be safe for the drivers. To make this mod you are putting your life at risk. I like my Xfire as is and I don't want to make her a ricer car.
Here is some review on Sprint Booster :

BTW I found on eBay similar stuff that calls Electronic throttle controller for $69 and I guess it does the same job as the overpriced Sprint Booster for $289.99
