So I just bought TSP stage 1 tune for my 2020 Si (Canadian spec - if that should help) and flashed it. After I flashed it, I went for a drive and started data logging. I started to notice on my gauge that the car was boosting way too much without going WOT.
I noticed 27.9 psi (target is 23.3 psi) peak boost at around 55% throttle in MAP 3 with sports mode and 24.8 psi (target 22 psi) in MAP 2 with sports mode at around the same throttle percentage. Is that normal? (I know it's not sadly that's why I'm making this post). I use 93 octane with 1.2 gallons of E85 to help with knock (been using this for almost a year now while I've been on Ktuner base map). It keeps my knock control down between 0.49 and flashes of 0.48 every here and there. Sometimes 0.50 to 0.52 when I push it a little and 0.56-0.59 max when I push it hard.
Also, I have PRL cobra cold air intake STREET maf but my fuel trims are always high AF. Even on ktuner base maps I had to adjust the MAF calibration to perfect it (0%) but that option is not available for me with this tune. I emailed TSP and they thought I may have a RACE maf without realizing but I don't.
I have emailed @Two Step Performance about the situation with datalogs and they're responding but because of work and their hours can't get it resolved in a day. That's why I posted it here incase anyone have had this issue before or if anyone know what's going on. Until then I'm going to flash back to my Ktuner base 23PSI map.
Here are pics of my maf housing.
Attached is the datalog.
Thank you y'all in advance.
