I think it depends on the tune and what you expect to get out of it.Does tuning generally require 93 octane?
TSP's site (https://www.twostepperformance.com/...stage-1-tune-for-2022-honda-civic-1-5t-non-si) for their tune says:Running 91+ will give the best results.
I figure it's like a weightlifter eating Sour Patch Kids vs. a Hungryman vs. chicken & vegetables. I'm giving my car chicken & vegetables (93 octane) because I want peak performance, and don't mind paying a bit extra for gas.Premium fuel (91 or 93 octane) is REQUIRED.
Thanks for adding your car.Tuning experience notes: I tried the TSP Stage 1 tune first (I ordered the KTuner from TSP, so the tune was included). It was good, but I switched to the Starter 21 tune, and changed all of the Quick Adjustments to the most aggressive settings, and according to my butt in the seat, it's way better... seems to have more power down in lower RPMs.
K tuner starter maps are great for dd's, when I had it I would never really pull to redline to get up to speed, now on phearable I feel I have to rev it out to redline compared to the starter maps. Not an issue though as it pulls soooooo nice up top compared to the other maps.Thanks for adding your car.
So TSP vs. an aggressive KTuner Starter...
In real numbers, the TSP tune is more powerful and smoother but they feel different. With TSP there is a lot of restraint down low with a more linear feel top to bottom.
The KTuner tunes with aggressive throttle, turbo, and spool settings will almost feel twitchy down low. Really fun. Has a nice midrange too. The downside is that the top end isn't as good as TSP.
The great thing about the included Starter tunes is the huge amount of adjustability to personal preference (although it may take some trial and error).
I'm basing that on my many years with both tunes on my 10th and I'm pretty positive the 11th tunes are essentially designed with the same feel.
Any footage of driving your 22' on the TSP tune?From my experience the TSP Stage 1 with early spool on is my favorite so far. I like the more linear power delivery and the pull on top end. I ran Phearable Stage 3 and 4 on flex on my 10AT 2.0t Sport Accord and it feels very similar. Besides the amount of power of course ?
