Fuel needs for tune

[Brock68]

I am about to install a Torrie tune on my 2012 MKS. Do I need to make any upgrades to the stock fuel system? I just had the fuel injectors cleaned. My engine has 37,000 on it. With just the cai, will y engine handle the tune? This is my daily driver and am a little nervous about longevity. Thanks for any input or advice.

No upgrades needed to fuel system if you are not doing an extreme build or planning to run E85 fuel.  You will need to run 93 gas to get the most of the best tune though.  No issues with longevity if you stick with established tuners like Unleashed & LME.  LET is another option. 

New plugs should be a requirement with a tune, gapped at 0.028/0.030.  Ask Torrie what he wants you to set it to, if the plugs are not pre-gapped.  Checking turbo piping to make sure all the clamps are secure is a good idea, as boost levels will be turned up.  If you "lose power", a hose that has blown off due to loose/no clamp may very well be the culprit.

Are you getting the 3 bar MAP tune?  If so, install the sensor first, then the tune.

Thanks. I am running 3 bar map sensor and 170 degree thermostat. I was not going to go with cooler plugs, but it seems like a good idea. Also, I received three tune files from Torrie.  Performance, performance firm shift, and boost. Any idea which I install? I hope to have everything done before the convention this week. Looking forward to it.

The plugs are not "colder", they just need regapped to a smaller gap to keep the higher pressures from "blowing out the flame."

You should try all three tunes, see which one is most in your comfort zone.  If wheel hop or hard shifting occurs, have Torrie turn down shift pressures to 190ish.  I suspect performance will be your daily driver tune.
