Tune needed?

[Stifler]

Just curious if a tune is required after putting hi-flow cats and MRT 2.0 on a 2015 LFX?

It's not "needed" by any means, but tuning after mods allows you to adjust your ECM parameters to better fit your mods, and can allow you to unlock more power than you would have with just your stock tune.

I'm currently running a Overkill e85/91octane tune on my heavily modded LFX, and Will has made a few adjustments for me so far. Data logging, tune revisions, etc are all included with the price of the original tune package.

Thanks for the reply. Just modding in steps as I can afford it. I will get a tune but might be a little bit of time between the exhaust and the tune.

You'll be fine for now without a tune. The more mods you add, the more a tune will complement those mods. I waited until I had almost every bolt-on before I tuned, and I didn't have any issues whatsoever. After going all bolt-ons, and THEN tuning though, big difference!
