TPI GM Tuned Port Injection Book.

ISO/WTB: TPI book, one of the aftermarket books will work,

I went through all my aftermarket books and I have all kinds but not that one, Just seeing if anyone here has one they want to part with,

Friend has a 70K5 rock crawler with a 383 and the L98 TPI on it and it's needing a little help Thanks All !!

Did he replace the fuel injector by any chance? The only new ones that are available are aftermarket copies (we make them) and they are terrible. It is usually the #1 cause of idle and rough running issues.
The only reason we haven't phased them out is that they're still in use on the long life Postal Service vehicles.
