UPDATE:

havent done much but i have made more progress on tuning
still playing around with my user tune low and user tune mid
i have been driving to work all week with a 15.0-15.8 afr
40 miles 1 way made my fuel mileage go up to 25 mpg lol i love it
but unfortunetly the TCCS isnt happy
so this weekend i will get into finer tuning to make the VF signal happier

also have a spearco replica fmic, 2.5ic pipes and blitz bov on the way

once the kit arrives i will bit moving my IAT sensor down to the IC area to prevent it from heatsoaking
right now at cruising speeds in 80-90 degree weather my IAT sensor is showing 125-135...which is making tuning a little bit hard lol

im thinking about a custom a/c setup
pretty much ill add a 2nd evaporator infront of my IC for when i want to put her through her paces
or may just go with a co2 spray bar...probably a better choice with less plumbing

Your long trip mpg will go up with cruise control. Long trip doing something like driving from the Buckeye state to SILV. Keep it 70-75 and you will hit close to 30 mpg. If you stay out of boost. Fuel trim will hit you if you can't control yourself.

thanks

havent done much with tuning...been kinda lazy

still need to figure out why tuner pro doesnt record afr, vf or rpm when datalogging
tried to uninstall then reinstall but no change
updated maft pro to 5.27 and no change
until i figure out that issue my cruise tuning will just go by drive and adjust user tune for a good afr

things i hope to accomplish this weekend:
install spearco fmic...as long as my used kit comes with all the couplers and clamps
replaced turbo to downpipe gasket
make and install test pipe to remove 2nd cat
move IAT sensor down near passenger fenderwell...currently mounted in 3000 pipe and will show 160-170degrees idling :)
read, read, read and read some more on my issue with datalogging

did a little work to the old girl
install godspeed fmic, rerouted IC piping a little, removed afm, replaced accordian hose with 3in piping, cone filter, install 2.5 in straight pipe exhaust from cat back, repaired a small coolant leak at upper radiator hose, replaced burnt out downpipe gasket at turbo, installed slightly bigger oil cooler, managed to bring my AIT temps down 15 degrees with new setup

Godspeed fmic mounted

How it sits today
p1854890_6.jpg

p1854890_7.jpg


Plans for later in the month are to make a box or snorkle system to help feed colder air to air filter

Also made some progress of maft pro....upgraded tuner pro to V5 and maft pro to 5.27...all datalogging is working fine
As far as fuel cut goes i need to purchased an AFPR to raise fuel cut...so that will happen later on this year

pretty happy how everything is turning out

**THIS IS JUST FOR AN IDEA...IM NOT RESPONSIBLE FOR ANY MECHANICAL OR PERSONAL DAMAGE


get ready for a fight lol
i found it easier to remove nose panel to gain all the access you need
with stock intercooler and afm setup my AIT was at 120 cruising down the highway...today driving to work with my new setup was a nice 105...so it definetly is cooling the air down better

what youll need to do to mount it like mine:
remove stock intercooler and oil cooler
remove brace from nose panel to panel above radiator(sorry brain fart) and it has 1 bolt that runs down infront of radiator
remove both horns that are mounted to above^^ bracket
you will need to cut the above bracket off...it must be reinstalled and bolt to nose otherwise your hood latch bracket is way to flimsy and may cause hood to open at high speeds
remove stock intercooler and oil cooler brackets
pop over flow tank out of your bracket
now the easy part is over with...its time to get custom ghetto :)

for the passenger side of intercooler i used a bracket that points up ontop of the crash bar...simply bent a piece of flat metal into where i want it(i used the stock intercooler/oil cooler brackets lol)
cut to fit...makes it easier if you have the car jacked up high...then use jack stands to hold the intercooler up
i pushed the intercooler as far up as i could...it still hangs about 1/2-1" below bumper with no stock lip..but im happy with how it turned out
p1854929_1.jpg

^^this is where i mounted my bracket to on the crash bar
p1854929_2.jpg


now onto the driver side of the intercooler bracket
again i went custom ghetto and used a piece of flat metal bent into shape and bolted to the long bolt that holds the crash bar to the front of car
p1854929_3.jpg


so with the mounted out of the way i originally want to run my IC piping like stock
i purchased 2 3-2 1/2" 90 degree couplers off ebay...heres the link to the 4 layer couplers
http://www.ebay.com/itm/330433179506?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

i had some issues with the upper coupler hitting the frame and not fitting correctly...i was worried about vibrations and coupler wearing a hole in itself
so what i did next was cut a section of the headlight bracket for a piece of intercooler pipe to run up and through the hole behind headlight(running it this way keeps you from closing your headlight :) )

for the turbo to intercooler i kept the stock outlet pipe in place and the small pipe thats bolted to the frame rail
you'll need a 2 1/4-2 1/2" reducer coupler

have fun and i did this in a 3 day period...im sure its do able in a day but i took my time

Lol thanks
If I wasn't an idiot in the beginning with my buffer wheel at work to sand old paint off
Then it would have a nice straight look
Took a few hrs to remove the low spots that I created with the buffer
Same with the intake lol

Now the old intake and valve covers that r on the car will be getting polished cause they still straight lol
