TMIC w/out turbo upgrade

I have uppipe and full trurboback and am working on turbo, injectors, tuning, etc. In the meantime, I am picking up a TurboXS TMIC I found for cheap.

Should I install the TMIC now? May be a while before I can afford turbo and tuning. Any reason not to?

You wont really pick up alot of horsepower with just a TMIC upgrade maybe 5-10hp at a guess. If you haven't already get tuning equipment like the accessport first.

Also i have heard that some TMIC dont have any benefits and some even hurt performance.

Huck,

You'll be fine if you throw the top mount on without the turbo upgrade. As far as some topmounts hurting u, well, I dont really see how that could happen. Without tuning, ur lookin at minimal gains but i seriously doubt it will hurt u. The tuning is where the upgraded IC's really shine. So seeing as you're picking up the top mount already, might as well throw it on. Only thing I can think of is maybe a tiny increase in turbo lag but i doubt it. For a street car, a good top mount is all u will need. A front mount isnt all that necessary.

As far as the tuning goes....I would just stick with an EcuTek....ive talked to too many people that have blown their engines with the piggy backs such as the Utec...and ive heard of a fair amount of problems with the accessport as well. thats not to say the EcuTeks are perfect...but ive had the best experiences with them rather than the piggy backs. my friends 02 almost blew because of the UTec because its just a piggy back, the ECU started to change things and was running it really lean. Hope that helps out Huckleberry!

Danka! I was already leaning towards EcuTek. But first the turbo!

And which turbo are u planning on using? If u are going to be driving the car a lot...I would suggest the VF34....i LOVE driving my friends 02 with the 34 on his, still very easy to drive and LOTS of nice power, hehe.

VF34 was what i was leaning towards. I'd rather have my power in the lower rpms than have a higher top end.

The 34 will give u both....nice top end with a fairly early spool! Very good choice I think.

also the 39 will... it's a good option now that so many STI owners are upgrading. Also there's nothing wrong with UTEC... it's obviously all about the tune/tuner, isn't it? Just have it tuned conservatively.

No, there isnt anything wrong with the Utec...it just isnt for those who do not know how to tune themselves because it will require constant attention...by constant i dont mean like daily or weekly, but it would be a good idea to check it from time to time, and use the maps from TXS only as a starting point...fine tune it to the specific car and it should be ok, just keep an i on it.
