2004 996TT Cab Stage I With EVO V-Flow Intake & EVO Short Shifter Kit

This classic silver 996TT Cabriolet came into us for the essential first phase of upgrades including the EVOMSit Software, EVO Diverter Valves, and V-Flow intake system with the Hitatchi MAF conversion kit as well as the EVO/B&M style short shifter kit.

There she is ready for surgery


Before adding the EVOMSit software with more boost and timing we need to replace the factory spark plugs with the improved Bosch units.


Off comes the bumper and the intercoolers in order to gain access to the coil packs and spark plugs:


With the new plugs in place the EVO V-Flow intake system is installed along with the Hitachi Mass Airflow Sensor upgrade (more robust).


The billet EVO diverter valves are also installed to help sustain higher boost.


The factory shift mechanism is both sloppy and long and as always we opted for the EVO B&M short shifter kit which reduces the throw and gives you a much more precise feel.


With the hardware in place she's finally ready to get some EVOMSit tuning magic with full calibration for 91 octane her horsepower jumps from the factory 415hp all the way to 515hp!


There she is with 515HP. She arrived with upgraded 996GT3 style wheels.
