Hello everyone,

I'm looking for a Bay Area tuner for my 85's new 350.
Timing, idle, and fuel pressure are fine and it runs strong, but it needs the PROM tuned to drive properly.

I'm in the East Bay, but can move it around the Bay if needed.

If not local, can someone recommend an online tuner? I don't trust any "performance" chip tuners, but if someone has positive experience with anyone in particular then I'll check them out.

Any help is appreciated.

Mark Roman is about the only one that can tune a C4 in the greater bay area. He worked out of MSI in Roseville. I had him to the initial tune on my ZZ4 when I dropped it into the 85.
