So i need to ask what is the rpm limit of my opti with OBD I? Just kinda curious even though my car barely gets to 6k rpm now.
Is it the PCM? or is it the opti-spark dist?
Is 7k rpm just a best guess or is there some dyno test data to support the actual limit.

I expect to need to now this limit for the future.

I like the idea of HP tuners programming on the fly
