FYI. I have had this kit for what seems like years now. Mine was the second one installed outside of mag as part of the pilot program. I worked with magnuson to resolve some initial issues with the tune and installation guide.

0 issues since the install. Runs fantastic with great drivability.

Could the tune be better for raw performance? Absolutely(they left all the toyota factory torque mgt in place to protect the driveline and trans) does it matter at all... nope, Drives great for what a 4runner is good at. It's actually better for it in the long run to keep it in place (most people don't uderstand this) If you want to race something or smoke the tires off the line... look for a different vehicle or plan on building up a trans and rear end... If you want to pull hills with ease and have plenty of power on tap with OEM like quality and a factory ECU.. It's a very nice upgrade to a platform that lacks power from the factory.

The URD kit may be great also, but this absolutely fills the gap in power from the factory. It's a joy to drive and worth every penny in my book.
