My comment was fully directed at the questions you were asking rather than what was on the car.

sorry guys, im really new to boost
ok so i dont want the 8:1 at all???
I'll spend my precious time and answer your questions in one post.
1. Turbo's generate heat. The air going into your motor will be nice and hot. Motors don't like hot air. Get a fucking intercooler.
2. FMU's are the cheap bastardized way of increasing fuel pressure to account for forced induction. It's like hiring a hooker to lose your virginity.
3. You cannot simply "tune" an ecu. You will need a daughter board if you wish to chip it or a piggyback or stand alone.
4. Wanting a 2-step for the sound of it is by far the most ricer and stupidest thing I have read in a long while.
5. An evo sounds like an evo, a sti sounds like an sti. It's the characteristics of the motor and exhaust that make up sound note (especially with the boxer motor in the sti). You will never have a 240 that sounds like either. Get over it now and stop sounding like a 14 year old that hopes they get a 240 in 2 years.
If you want the super cheap (yet still proven to work) way to go about getting your shit running then follow my instructions:
1. Pick up an intercooler and piping. If you get a shop to do the piping and a FMIC from ebay shouldnt be more than $300 (probably less, havent shopped around for those in the past year or so but for my build I got top end and it ran me 450$).
2. Pick up a safc-ii. quite possibly the most terrible piggy back ever, but it will get the job done for your needs (since you dont seem like you will run more than 7 psi). Should be somewhere in the 100-200 range.
3. Get SR 370cc injectors. Gonna cost again 100-200 i think.. probably cheaper though.
4. Get a professional tune by a trusted shop. On a safc-ii should be no more than 75-100$ for a full tune on a dyno.
