Not entirely. Has an AFE closed box intake with turbo inlet, and Powerflex lower transmission mount bushings to help prevent wheel hop. But I was mainly testing the JB4 on different maps. The first run was on Map0 (stock), but the second run on Map2 was the best time with higher mph. JB4 didn't make much difference, but still, any little bit helps. Saving up for a EK1 tune instead and then I plan to go back.
Is the EN stock ?
