Open air filter, helix downpipe, test pipe, HKS catback, SAFC with corrections set to 0. I know that a previous owner had an UICP with stock battery, and an exhaust. Guess that's as good of a place to start as any! Anyone know what the outside diameter is of the section where the intake pipe connects to the turbo? I'm going to throw together another one of my fabulous boost leak detectors 
i would flash the ecu and you could add a couple more things if you wanted to before you get the flash. especially if youre planning on adding them to the car soon. i got my flash through dynoflash. i got better gas mileage, ridded of the speed limiter, rev limiter, and fuel cut. i got more power out of it as well. buschur racing also does good ecu flashes so you could check into theirs.
My evo idels at 800rps when its warmed up! sometimes with will drop down and then bounce back up.
MY gas was **** when i got my car used at 20k miles someone before me tuned it with a AFC so i went to a shop and got it tuned for 200 bux and the car got a little more power and a lot better gas.

w8lifter21 my mileage sucks about as bad as yours does. BUt mine didnt alway suck this bad. I used to get between 240-260. now I am lucky to get 200. I have to do the boost leak test and check the plugs. the car does not feel weak but it sure does suck having to fill up 1.5 times more each month...btw I have been using the gas from the same shell station almost the same pump every time for approximately 1 year...93 octane
get other mods befor you spend money on a tune, i went with a tbe without tune for almost a year and still got an average of 23mpg and i like to have fun when i drive, i wen ahead and got cams, meth, intake, ic piping, fuel pump ect then got my tune and wow what a difference, good luck bro
I'm on the stock motor. Just a bolt on SBR 3076 HAFE kit and 850's tuned via ecuflash. I have mods in sig.
I'm running about 1.4-1.5 BAR on it.
It totally balanced the car out. No more meth head stock turbo, and boost when you don't want it. I still see 20psi in 3rd around 3800/4000. And pulls 200% better than the stock turbo on top. And I get alot better gas mileage when my foots not in it.

Yeah that's the plan, but 15mpg is KILLING me. I definetly want to get cams, fuel pump and a few other misc little things, but there has to be something wrong or a tune for mods that aren't on the car anymore.

Is it ok for me to run a GT35r on stock block, valvetrain? This next question is going to be very noob like, but, what power level can I expect to be at with that kit? I'd like to squeeze out as much of the stock turbo as I can before taking the leap to bigger and better snails .
