Plan on going Cobb stg3
I plan on going cobb stg3 with the STI TMIC and VF39. Do you think I should save my money and buy a FMIC and then get a protune?

There is no stage 3. There is 2.5 which is a VF34 + fuel pump and injectors for 2002-2005. The 06s have bigger injectors stock though, and I do not think there is a 2.5 map out for the 06s. If I were you I would get a simple stage two, then save up for an 18g FMIC and other supporting mods + protune.

A FMIC won't really do much of anything for you with a VF39, I don't think. A TD06-20G (or maybe even 18G) would be a different story.

Cobb just posted dyno's of their stage 3 maps, one for the VF39 and one for the Td06 18G. Both have nearly equal power and torque with the VF39 having more torque and the 18g having a little more hp up top.
Either way I'd save for a protune and skip the FMIC, neither of those turbo's are going to be supporting enough hp to warrant anything bigger then the STI top mount Mike |

Sti top mount is crap. 18 is much bigger than the vf39 and IMO does warrent a fmic

This thread got moved to the 2.0 forum but since it's about a 2006 TR, I'm putting it in the 2.5 forum.

The 18G *should* make way more power than the VF39 if the rest of the engine bit can support it. It flows, what, about 50% more air? I'd guess that a) a conservative tune, and b) the STI top mount are really holding it back. Even with just a bigger TMIC and a tune should have an 18G killing a VF39.
