Failing that, just go the to the dynapack. Good to learn about tuning, but if you want results rather than an experiment, best to stick with someone who has prior experience to make the adjustments and then learn from them

Going from 94 to 93 shouldn't make much of a difference -- going to 91 might tho'...

I'm just concerned about having to use 91 octane when the car was tuned for 94 octane. Worried about knock, etc.

I'll have to see about tuning/tuners, it's really hit or miss in Ontario... Although my neighbour has a high 6-low-7 second "street legal" 63 Vette, I'll have to ask him who does his tuning.

Ask them how much timing was advanced. From my own dyno expereince, the Z doesn't seem to like much extra timing up top, so it may only have a degree or two -- that should be okay -- but best to check with your tuner.

I've been told that the motor has a pretty excellent knock detection system, and can adjust timing and VVEL to keep the motor running safely, so it may not matter at all.

At worst, it's a simple matter of just scaling back the ignition map by 1 degree at full tilt for extra safety.

That said, if the temps are getting cooler out in your area, you have even less to worry about.

Is the timing something I can check with Cipher or Osiris?
