The stock LBZ turbocharger on your 2004.5-2010 GM 6.6L Duramax runs out of air at about 530 RWHP, leaving a lot to be desired when it comes to your high-performance applications. It also has trouble controlling EGTs on extended pulls past the 400HP mark. If you need room to modify your Sierra or Silverado and support the extra power, pick up the DuramaxTuner VVT Stealth 64 Turbocharger. This premium upgraded turbocharger is capable of running up to 650 RWHP, giving you a ton of room when it comes to any performance modifications and tuning. Moreover, the Stealth 64 VVT is much better at controlling Exhaust Gas Temperatures under heavy loads and up long grades at high power. This is accomplished through the use of the specially designed billet compressor wheel which is perfectly matched to the higher flowing turbine assembly. When everything comes together, this turbo provides the perfect balance between quick spool-up response for drive-ability and overall compressor flow for peak power whenever you need it.
