Awesome build man. My car is going to buschur in a few weeks for a 2.3 black set up. I have the ams street fmic and it was said to ditch that for a buschur race core. I guess I was so oblivious to how different these fmic can be. CBRD seems like they are good to work with, I plan on taking my car there after I get it back just to fine tune it.

thanks.
Im about 10minutes from cbrd. im close to york. you should come to one of our meets.. i plan on attending one soon with Adam (Batty) to shut down some domestics 
lots of guys around here still dont know what evos are capable of 
thanks.. your numbers feel no different then what i got tho, so youre not missing much.
anything past 460tq feels great in a evo. I would run the stock block until it throws a rod.. its not worth doing a engine build. If I could do over i would have ran the stock block until it blew up, because the built motor whole ordeal gets expensive quick. Or do drop in pistons, rods, etc.. no need for a entirely new shortblock.

Heres an update. I installed the new fmic ( Buschur race core 3.8" Garrett) and found the following:
1. The intake air temps will raise because the FMIC is bigger and will restrict air from reaching the radiator as easy as a 3.5".
2. Much more pressure drop. Example: 39psi spike drops to 30psi at redline, where on the perrin it would hold 33-34.
3. Pulls seem to be very consistent now within 1-5whp vs the perrin 20-30whp. This tells me the perrin was heatsoaking and the new race core is not. (seems to be due to ecu pulling timing due to intake air temp vs timing tables / not fmic related 8-14-2010)
4. Dont ask me why or how, but with tweaking my tune I picked up 400rpm faster spool, hitting 39psi by 4000rpm vs 4400rpm with the perrin.
Now for a quick temp tune job I did. I did not like the way the car felt downlow with the dyno tune, so I redid the entire timing map downlow and picked up way more power and response and continue to use the timing that I was given from 6500 to redline since that seems to be dead on the money. I suspect the downlow tune was off due to the hot day and the perrin heatsoaking + the ecu pulling craploads of timing. for example, If we set 2* somewhere, the ECU would only allow -1* and so on.. so it mangled the tune on the road. Thankfully I know how to fix it myself and the car feels very responsive again down low and is a torque monster again.
Im going to do some more tweaks then i will go back to a dyno and confirm the results. for now here is Virtual dyno which is very accurate from what Ive researched and gathered.. and its clearly obvious the car feels way more awake downlow.. before it felt sluggish. Also on the dyno graph it showed gains everywhere, so it is certainly not kreionics fault for the lower portion of the timing map being off.. he is a wonderful tuner and worked with what i gave him, and thats all that matters.. everything from 6500rpm on up is pretty much dead on the money
heres a 39psi spike tappering to 31psi. I did this last night, i may have to pull afew deg or add a deg or so to make more power but this is a very quick 1 time edit of both maps and go out for a pull and received these results.. i need to clean the a/f up but its pretty close.
Before pic is perrin with dyno tune at 37psi - after is buschur fmic with 39psi and my tune + kreionics timing from 6500 to redline.
I have a new goal to make, its to hit 600wtq which I believe I can do, but might blow the clutch up in the process but at this point i do not care. next time i post a dyno thread here expect to see 600tq lol.

u want to see 600 now? maybe i could do it if i turned it 3 turns but the clutch might go through the firewall and chop my legs off also then you wont ever see numbers now its your turn. im always here to help you also.. you know that
you help me with style mods, i help you with other stuff.i think the car will do good at the track because it has pretty good traction and my setup seems to work well.

Thanks man. Ya I love torque.
yep 10.8-11 seems to give some more unf down there, and 2* makes much more torque vs 1* on my car. Im gonna experiment more on the a/f see how lean I can get it down there without sacrificing torque.. of course i will contact you on google talk after or as im doin this
next up will be ams f1i or magnus v5.. over the winter of course. for now im gonna enjoy it. From my research I've learned bigger runner intake manifolds are major increases in power with stroker motors.

The reason is because I am wondering if the fat AF that you used at peak torque allowed a slower burn, putting whatever timing numbers you were using closer to MBT, producing more power.
E85 has been known to not take that much timing down low at peak torque...more similar to pump gas than race gas whereas it can take craploads of timing up top.
If this is true, be careful leaning it out and potentially going past MBT. An easy test would be to lower the timing and see if your torque goes up. But anyway, very interesting data and I'm interested in your results with different AFR and timing in the spool/peak torque area. There isn't that much data for these kind of things on E85.
Awesome results btw. The car must be a blast to drive.

I was being stubbern. I should have got it but I didnt. 
Will do man. I was gonna go out and slowly lean it out and do back to back pulls to confirm the changes. I will do the leaning out with no timing changed first and then i will pull more timing.. do you want me to target just the peak torque or do you want me to lower it up to around 6k? let me know. Thanks btw
If you're on E85 and you lean out the spool/peak torque area, do me a favor and try lowering the timing too.
