Couldn't be happier with my tune from Dave. Car is supafast now, only thing faster is Dave with his revisions. Power mods were:
catless dp
catless up
3-port
BNR 16g
Turbo spool is quicker and more responsive than stock. I also never realized just how badly the stock VF40 falls on its face in the upper rev ranges. The 16g maintains more power through the whole band.
I hugely appreciated Dave's emphasis on making power safely. He checked with me to make sure all my hardware was in order before I started tuning, and added power in a safe, incremental way. I felt like he took the same care he would tuning his own car, so I would recommend a Cryotune for anybody.
