Colder weather, lower boost?

Post by Suntzu »

Hello,

I have a Honda Accord 1.5T CVT 2021 running on stage 2 since April this year. It's low 60's this morning while I was on the road for work. I noticed it never hit more than 13.5 psi boost compared to when the outside temperature is >=70F. I'm on 1000' above sea level. Is this normal? What is the idea behind it? Thanks in advance.

I did a quick pull on lunch time, outside temperature is 75F. High boost is back!

Have you reflashed since April? I see you've updated your software at least. If not, you should try that.

Yes, I have reflashed on August 24th as I had to reflash to factory and unlock on August 23rd for my first dealership oil change and inspection.

Any more ideas? Should I reflash again?

If your Max RPM was 3500 you don't really have a full test there, so I'm not sure what you're actually gauging on. Beyond that feel free to try to flash again if you didn't do so properly.
