ProECM Powerchip was removed since my last dyno run. So here's a 3rd gear comparison of my ProECM installed from 2 weeks ago vs my best 3rd gear pull today (both with the JCSports intake installed). Also note: Today's JC Sport intake had a brand new K&N filter while two weeks ago had a used filter intalled.
