Hey all. Just had a big bore install with cams and will do dyno tune after break in is complete. I will be at about 20k miles when break-in is done. My question is, should I do 20k service first, then do the dyno tune? Or do the Dyno tune first then do the 20k service?

 

Tune first, then the service.

 

You do know that your Tuner can break in the motor while doing the Dyno-tune?

 

That is a very good method, as much can be monitored during the process.
