Im new to this forum. I also go to www.ls1.com because I own a z28. Was wondering if there are any easy mods for the IS 300 like the ls1. For example: Pull out screen in maf to trick computer into thinking there is less load on engine thus increases timing. Some say it leans the mixture. Cut egr tube that extends into the throttle body. Are there any easy mods to increase performance of the IS?
