We don't recommend any sort of 87 octane in these cars at all. Not even the factory tune. We give IAM alot of range but the knock correction range will be severe even in the cruise range (off boost). Most off path gas stations around here have at least 91.

I would limp it as much as possible to the nearest 93 station.
