Default is 12.5 a/f safe at 7psi....funny story.

Well a friend of mine was in despair over his new turbo set up not working right.... i siad i would give it a quick tune for him to get it going. well he has stock injectors, and doesnt seem to care if the motor goes on him.

Just for the record stock obd 2 240cc from a b18b will do alright up untill about 7000rpm and 7psi. I only spent about an hour on it , tried to make it as safe as possible....i give it a week before its toast.

Any who 12.5 a/f at 7000 and things go bad from there. i thikn i will set his rev limit to 6400 and a speed limit to 80mph just to save him the trouble......or let it go sky high.

turbo is a china t3/t4

Why even waste the time and money to install the parts and not get DSM injectors for cheap or something.

It's not about the PSI, it's about the tune and the amount of power being made. Your friend is straight up retarded BTW.

The setup itself is obviously way unsafe but IMO 12.5:1 at 7psi is fine.
