We began the modifications in 2005 with Headers and a tune. Several other things were done including subframe connectors, GMM Ripshift, and a 3″ custom Muffler systems eventually deleting the cats. We added heads and cam in 2005 and in 2006 added one of the first LS3/LS7 Maf Sensors to a 4″ CAI. By that time we had 3.91 gears in the rear of the car and Monster Clutch Company had developed a stage 3 clutch that would for the first time, hold the power of the LS1 engine.
