APS Extreme Duty Twin Turbo System
 

Do any of you guys know of this? http://www.injectedperformance.com/V...ID=4439&VID=36
I want to get it it looks great over 500 HP for just that mod? This is impressive is it possible to get over 600 HP with that turbo kit alone? (my target HP)

we have been told that if you use something like the Magnetti Marelli for fuel management, these kits are capable of every bit of 800 horse. We have not seen it done yet, thats just what we have heard.
