Where to set timing with 9psi powerdyne

[Jeff Chambers]

You don't say what PCM you have, which would tell me what kind of total advance is being commanded. The 9psi PD kits rarely make 9psi, usually more around 5 or 6 so at that point I'd be looking to retard the timing 3 or 4 degrees under boost; total timing probably around 27 to 29-degrees. This of course depends on what your compression ratio is in the motor. The car's going to run off-kilter until you get a tune on it. I'd find a dyno tuning shop in your area a make an appointment for a custom tuning session.
