Default Re: Dyno runs. Good and bad 2003 SVT lightning

Big difference between the KB and Apton. 2.3 vs. 1.4 roughly. The KB will made a lot more power. We should have a KB equipped 5.4 finished by the end of the month with a Stage II JDM.
Be careful on boost levels. The stock valve spring (based on testing) will float the valves under too much boost.

I think you will be elated with the KB.
