    How does a dyno tuner tune a chipped P28 ECU?

    Getting a dyno tune this week and I can’t find any post on how dyno tuners tune chipped P28 ECUs. Do they use a live chip reader and plug directly into the ECU and use a program like Neptune for example? Whoever had their car dynoed and has a P28, can you tell me how that worked?
