Heat cycle the new valve springs a few times before you get high on the rpms.

Can you elaborate what do you mean by heat cycle the valve springs? As in put some miles on them or what?

I probably will have the car re-dyno tune in about a week or so. Depends on how many miles I should put on the new springs

You can let the car idle up to operating temp & then shut it down.. Let it cool & repeat process once more.. Generally two heat cycles is enough.

Is driving the car several times count as heat cycling the springs? No hard driving yet though, I've driven around 40 miles with the new setup now going and back from work

As long as you've let the car completely heat up and cool down 3-4 times, you're good to go
