I have the slp lid,obx headers,magna flow exhaust, y pipe, k&n, already placed on a stock 2000 ws6. I have a ls6 intake, 80mm maf, n slp under drive pulley pending to be installed along with the tune. I was wondering do I need to go bigger on the throttle body or will the stock be fine. Thanks for any advise
