06 Model and just did 5" Turbo back exhaust= Predator programmer on extreme setting - and Afe complete intake with tube to turbo. Truck sounds awesome and can really tell a difference in power just not getting the smoke I want!!! Will smoke a tad bit at take off but thats it. Still got the RKL tune left to try but not sure if it will make that big a differnce or not. I know smking isn't making power but would like to see some!
