Yukon 5.3

[ndestounis]

I have a 2004 Yukon SLT with a 5.3, I have added a K&N intake and a Magnaflow catback exhaust. I would like to run a performance programmer that will not lean out and cause detonation. superchips and Edge have old me their products are not recommended. Would like to hear from any one that has a set up like mine or knows what product to use.

There are many guys here including myself that have a custom tune from http://www.blackbearperformance.com/

Don`t bother with a handheld tuner. They can`t compare to a custom tune.
