Has anyone tried the SprintBooster yet? I seen it on ebay. Looks cool, interested if it really works.

 

I personally would never install this on my truck.. God only knows what kind of electrical problems this could give you... Plug and play but I wouldn't trust this. Put your $$$ into a tuner where it's customizable or pre programmed. If you have a 09-10 that is... If you have a 2011+ just wait for the tuning to come out...

 

I ordered 90mm throttle body, intake, programmer, and exhaust, I thought about taking it to high desert speedway this summer, if it shows any promise. Just wondered if anyone had tried it, it claims a second of difference.
