Hello I am looking to start upgrading my 2013 sonic LT 1.4t, and I had a few questions. First off as of right now im looking to get a ZZP downpipe and full turbo back exhaust, along with the Trifecta tune. But how does Trifecta do their tunes? Do they just base it off the stock 1.4t setting? or if i had upgrades like the turbo back exhaust, do they base the tune off what my upgrades are. Also when i replace the downpipe i was reading that i will get engine codes does can Trifecta work around that and adjust the o2 sensor so i wont get the engine code? I will be calling Trifecta but i wanted to see if anyone knew about it so i had some insight before calling.
