Ok so I got a j pipe, precat, deletes, takeda intake, and a ktuner. I am thinking getting a 3.7 intake and p2r runners with bigger throttle body befor I get tuned. What I am looking for is if there is anything I should do befor that stuff. Or would you just tune it how I have it now and add the stuff and then tune it down the road. Thank you for any and all info.

 

every time you add a mod, you should tune after to REALLY dial it in.

that's what a tune is doing...the tuner is analysing the data and fine tuning it.
