Nice list, but where's the vf39 from the sti?

Imagine it would be right where the 30/34 would be seeing as they are ussually interchangable with minimal tunning

seems the 30/34 are strangely close to the 22...I thought the 22 flowed [email protected] 14lbs
Admittedly, I know little to nothing about turbo's and CFM flow, etc. But I spoke with Christian from Cobb and asked him if the new vf39 Xt map could be used for a vf34. He said from his dyno testing, that the vf34 is not suited for a 2.5 liter engine. He said it falls on its face at higher RPM's... much like the stock turbo, but not quite as bad. Just thought I would share.

I think he tries to make them look different because he doesn't want to 2.0 turbo guy's using it on there vf30/34 maps. But the ones that have said they work perfecly.

If I can find one for a decent price I would much prefer it to the vf39, so I won't have to worry about the cracking problem
