I wanted to create a dedicated thread specifically for the results of this install along with the necessary tuning I will do in order to account for this item on my stock turbo STI.

Maiden Voyage: My original TMIC tune is still in place. The initial drive came a litter earlier than expected since I had to go pickup the kids from grandmas (wow, what a way to start off a FMIC thread - lmao). I got to sleep in this morning until 9am! Sweeeeeeeeet!

Overall, under 5psi I couldn't tell an on-throttle difference. However, off throttle, the RPMs seemed to spool down a tiny bit quicker (as if you had the AC on). It wasn't near as evident as if the AC were actually on - but I did notice it. Overall, the car drove completely normal. Over 5 psi (but still part throttle) I could tell I wasn't getting as fast a 'hit' as I did previously. Don't get me wrong - this was not something very noticeable. But, I wanted to list all my observations. Moreover, this isn't that surprising since I am using 0% wastegate duty at 30% throttle and less. So, no big deal. I didn't get to do any major WOT pulls yet. I did three 2000-4500rpm WOT pulls in 2nd gear on a deserted unused road (c'mon, I had 2 kids in the car). My target boost was easily hit. Overall, with my TMIC tune, the FMIC felt like I had installed a slightly bigger turbo. It wasn't the 'insta-boost' like with the TMIC. It was slightly behind what I had with the TMIC but, when it hit, it hit hard and pulled really well (for that 1000rpms - rofl). Don't over-interpret what I mean by slightly bigger turbo. It wasn't a huge difference - but it definitely was something noticeable. Again, keep in mind that this is on my TMIC tune - nothing has been done with regard to tuning for the FMIC. I had a huge grin once the power hit. It definitely felt better to me (and my kids were screaming 'weeeeeeeeeeee' -- they really love this car).

So, that's my initial impressions of how the car reacted on a TMIC tune. I'll have more reactions in higher gears and higher RPMs whenever I get a chance to test. I have the kids all day today while the wife works on her master's program. Thus, definitely not today.

For the real truth-teller, once you get tuned for it, and have everything where you think it kicks ***, toss your stock TMIC and a TMIC tune back on. I did this and is why I will NEVER go with a FMIC again, but I'm tuned in for the details just the same.

^^Well with comments like that, you make this very interesting. Its too bad you couldn't have had a dyno run before the swap. Butt dyno will have to suffice, and I'm all ears. Subscribed

I would have loved to have dynoed it. But, I just can't spend $100+ on each dyno session. That would be about $250 to dyno before and after . It's just too damn expensive around here. I need a company to sponsor me dyno time ... .. . or to win a lot of money so I can buy my own dyno.

As far as the butt dyno - don't believe me . Seriously. Butt dynos lie all the time. Plus, all I did was some crappy initial pulls. I need to get some seat time in this puppy on my stock TMIC tune in order to really see what I think.

Now you can up the WGDC and lock it down low to get back that spool and run more boost like me Then you can go add some more timing since it will hold it better now with the cooler charge since the timing I saw you running before seamed a bit weak

Once mine goes on I don't think I am going need to make any changes since my setup is pretty aggressive as is. Hopefully it will help better deal with the surge in higher gears that the TMIC couldn't handle.

nice impressions, thanks for sharing.

sweet. cant wait for the results.

Scccchhhwwweeettt.

The plot thickens.

Ok. I have several WOT runs under my belt now on my TMIC tune. Impressions:

1) Car goes about a point richer between shifts. You can feel this. Feels icky.
2) Car spools slower between shifts. You can feel this. Feels icky.
3) Car takes a bit longer to spool up when smashing the pedal to the floor. You can feel this. Feels icky.
4) Car doesn't hold boost at redline like it did previously. I can't feel this. Feels fine. However, MAF volts are down by ~0.05.
5) After boost hits, the car feels great and very peppy. Feels nice.
6) The intercooler stays cool all the time when previously it would be warm.
7) Car definitely does drop quicker in RPMs between shifts (analogous to having the AC on but not nearly as evident).

So, overall, the car is slower. The car doesn't feel as torquey. I really like it when boost hits. However, the negatives outweigh the positives at this point.

Conclusion: If you have a ProTUNE on your TMIC setup, do not run a FMIC on that tune unless you want to have more negatives than positives. Of course, I had a truly kick butt TMIC tune

Time for me to start tuning.

So it is true....

Seriously...thanks for spending the time and money to prove this.
