That i do not know. Unfortunately i have no information on this. I purchased it used from a local Dealership. I thought maybe it was tuned with E85, but i do not know.
I just recently purchased a 2021 supra 3.0 with 10k on the ticker. When i picked it up i noticed it had the E85 smell. It does have bolt ons. I have noticed this weird stutter almost like a hickup at idle when i start it. Its suttle but quick to make the car shake a bit. Kinda like a missfire...
