What Mods require a re-tune

[vernonator]

I am running Livernois tunes (4/93) on my stock '12 PP SHO. I am looking to do some physical mods this spring, non-catted downpipes, 170deg thermo to start with maybe others to follow. What mods need a re-tune? I know things like Meth, upgraded turbo's etc are on the list, but what else on there?

Thanks guys...looking forward to some more hp in the SHO

You'll want to get revised tunes for the non catted pipes and tstat.

Right on, you are doing the same mods I'm doing, we'll have to compare performance! Haha. As DJE said pretty much any of those mods require a revised tune, but as I understand it, all you have to do is let Livernois know and they'll send you and updated file.

Just to get the terminology straight... The downpipes and T-stat don't "require" a tune mod... but if you want the most performance enhancement from these mods it would be best to get a tune adjustment.  The T-stat, as well as the spark plug change to lower heat range with re-gap is recommended. For these mods LMS and Unleashed can both do this for original tunes files when you order or as free tweaks to tunes of existing customers.

The OP mentioned getting catless downpipes which would require a revised tune to tune out the O2 sensors.

True

Correct. You will need revised tune files for all of the following:

- Our Downpipes ( Catted/ without cats)
- Our Thermostat upgrade
- Our 3 Bar map sensor
- Our Meth Kit
- Our Upgraded turbos

Brandon.. in the tune for the downpipes I understand the lower O2 sensor is turned off, is performance affected by leaving it on?  If so, how much? 

Is your 3Bar sensor the same as the Ford 3 Bar?

The only thing the rear O2 sensors do is throw a code if you don't have properly working cats.
