Tuning your 11th gen is definitely the single best power mod there is. A tune totally transforms the car. But what about long term, every day reliability? After all, tuning does add some additional stress. This thread will document just that as well as owners overall tuning experiences.
If you own a tuned 11th gen Civic help the CivicXI community and add your car to this thread (Si, Type R, Non-Si 1.5T, 2.0 NA).
Use the format below when adding your car:
Vehicle: 2022 Civic Si
Total tuned time: 7 months
Tuned miles driven: 5,200
Tuning device(s) used: KTuner V1.2
Tunes used: TSP Stage 1
Fuel used: 93 octane
Additional related mods: PRL Stage 1 intake
Problems/issues: None
Driving style: Aggressive bursts here and there
Tuning experience notes: Best bang for the buck ever.
At the end of your post you can include pics, vids, timeslips, dragy results and dyno sheets.

Thread Notes
Some Si owners (7) have reported minor clutch slip issues on OTS tunes. For this thread, FBO is considered intake, intercooler, downpipe, frontpipe at a minimum.
Reliability Tips
• Due to potential long term issues, octane booster and VTA blow-off valves aren't recommended.
• Flashing a tune is battery intensive. Always connect a battery tender/trickle charger if possible.
• If you don't have a trickle charger, go on a long drive before flashing to ensure the battery is well charged.
• Running and reviewing occasional datalogs may spot problems before they become costly repairs.
• Never use gas that's a lower octane than your tune's minimum requirement. Use top tier gas.
• Using boost by gear can help improve traction and protect CVTs by limiting torque down low.
• CVTs should never be brake launched. Try to limit wide open throttle pulls from a stop.
• Always wait until the engine hits normal operating temperature before any spirited driving.
• Consider using a fuel system cleaner annually, especially if not using top tier gas.
• Don't self-tune your car. Leave those tuning tables to the pros only.
• It's always a good idea to change oil and fluids sooner than factory recommendations when tuned.
• If your car throws a CEL, get it properly diagnosed and fixed as soon as possible.
• Avoid going full throttle in overdriven gears. Lugging the engine like that can potentially cause damage.
• If you have elevated knock control it's likely bad fuel quality. Try a different and busier station.
