Most of the RPO codes are rubbed off, I can only see maybe 1/2 of them legibly. Gt4 LO5 f44 are the important ones I think. But BJLH is associated with 16197427. if figuring this out is this confusing tuning must be a treat.... I have megasquirt on my VW Baja turbo build so I'm not completely in the dark
