I’ve got a ’22 Supra with a CAI and catless downpipe, but no tune yet. Do you think it’s fine to run like this for a couple months (or even years), or am I risking issues? If I do decide to tune, I was considering JB4, would that be enough, or is it worth getting the ECU unlocked instead?
I’ve got a 2022 Supra A91-CF, bone stock with the OEM duckbill, etc. Thinking about swapping to a Street Hunter spoiler and maybe adding a carbon fiber hood/roof.
I want to keep resale value high. I’d save all OEM parts, but will mods like these still turn off buyers or drop the price? Should I...
