During the morning Dan Harman showed me where boost was spiking @ 5500rpm. We knew tuning would not control the mechanical limitations of the wastegate - BAD. He ported the vf39 and an hour and half later was tuning again - GOOD. Dan has ported almost 50 of these turbos so take it from me, you can trust his technique and experience. Dan was confident, honest and made me feel comfortable about the resolution. Besides being a great tuner he actually has a funny personality. Oh yeah, Stella the gal that works there is super cute and spunky :rofl: did i just say that?
Big props to Boataholic! He was a great help with the inlet and plug install. I OWE YOU!! Also, his friend Chris let us use his auto shop all day Saturday with access to every single tool known to man. C00L!!!
