ive an 04 265bhp sti.
im looking at the different tuning packages to get 350 bhp any thoughts

 

You're at the limit of the turbo (VF35) at around 330. So you would need trick mods or addictives to get to 350.

What is your budget & aims for the car? That's the best place to start.

As a whole, the TSL333 package is well respected & documented.

 

I guess in pure "specification" only terms, there will only be seemingly minor differences between what is changed or done.

As the longest established Impreza Specialist around, I think it's fair to say that having the correct job done is more than just the sum of the parts used.
HOW it's done is just as important if not even more so.

By all means, shop around, there's too much detail to post in a thread like this based as much around the things that we don't do, as much as the things that we do, these are the bits that put us "at the top of the tree" in this area.

Give us a call if you wish to discuss?
