The most popular turbo upgrade for the 996 Turbo is taking the OEM K24 turbos found on the x50 or GT2 and having them modified with an 18G exhaust side. This turbo setup then produces the same low end turbo spool of the K24 but with a huge increase in the mid to top end RPM range. This map is designed to run using 60lb injectors and an electronic boost controller. Inconjunction with corresponding mods, this ECU tune will take your vehicle up to 650HP to the crank. Modifications should be consulted with a installer and the assistance of VR Tuned to maximize the potential of your vehicle. The tuned file is designed to eliminate the factory boost controller and raise the factory boost cut from 1.3bar to 1.6bar. For those running catless race pipes, VR Tuned raises the O2 limiters which trick the computer from throwing a CEL. This map is available for a 91 octane or 93 octane pump gas car as well.
As tested on a 2002 996TT Tiptronic, this car made 529awhp and 532ft/lbs of torque on a Mustang AWD dyno. With a 25% drivetrain loss, that is a 661hp to the crank. The car was equipped with a high flow exhaust system, boost hoses, cold air intake, diverter valves, boost controller, 60lb injectors, and running 1.4bar on 109octane race gas.
