So, with a bit of a dilemma in my mind, I thought I would pose this question to the pros on this board.

I have currently only the ZZP Catless downpipe. Future plans include upgraded intercooler and piping (hot for sure, possibly cold as well), the ZZP CIA (depends on price and performance gains), external BOV.

Should I purchase and install all of the bolt-ons first and then get the Trifecta tune or should I tune first, then piece together everything else, and re-tune for everything once its complete? My reasoning being, the learn down feature on the stock tune will limit any performance gains (noticeable already with my downpipe -- it was very noticeable on butt dyno for the first few days, now I just have a great sound) I would get with bolt-ons. So, why not tune to remove that and then piece it together.

Any thoughts from you guys/gals that are already modded and have a lot more experience than I do?

TIA

 

What I did was I got all the bolt ons first and then tune. It work out pretty good for me. It is always smart to do the mods first and tune for them so you don't have to keep retuning every time you change something.

 

 

Yeah, that's kind of what I was thinking. I just wasn't sure if the "learn down" feature should factor into my equation.

Does this intercooler upgrade/piping upgrade require a tune?

 

no.
