Okay...been here before but, Do I send my computer off and have it flashed for Turbo boost or do I go old school and solder the chip? K&N cold air kit has been universally endorsed. But...I'm getting 2 opposing opinions on the Turbo: Flash and risk having it wiped out when I go in for warranty work or solder and replace the chip everytime I go in for warranty work? Both are asking 3 days turnaround time....send/return computer or solder/install. (FYI: 2004 w/ 20K miles) Also...can anyone confirm that I'm looking to gain 25hp and 40lbs torque? Thanks.
