U may need to get it dyno tunned, with some sort of ECU up grade, but i read a sheet on dyno with gsr motors with Type R cams, and SKunk2 cams, and u get more power with the skunk2 cams, ( Skunk2 intake, SKunk2 cams, Comptech headers, Comptech ice box, apexi n1) [i have to get it dyno tunned and upgrade the ECU or get a VAFC]
