i hate to even ask this.. im a total car guy. form those words alone you know i was bread on american muscle... im real new to the subbie family.. ive gotten nothing but love from you guys lately... i just bought an 05 sti.. and have a ton of questions... first i know what the DCCD does but like the nova monkey i am when i switch of auto what do the arows indicate.. th more green the more rear power? and what about lock?? ive never owned a car this pricey/nice... im just trying to take care of her.. i live in upstate NY work hard for the money adn had to buy a car the would keep me happy in the summer but go in the snow.. any advice on mods or info on my car you can give me would be awesome thank you very much.. links to vendors or info on my car would be greatly appreciated.. lovin the subbie!!!! STi power wil kick american any day between you me and the fence ;-)

 

In "lock", which is essentially 50/50 locked power distribution, you will get diff noises when turning at low speeds. From personal experience i get it even in one setting above full rear, so i don't really mess with it, i just set it to full open, which is the rear most setting at 35/65, and go to town with it. You will notice a considerable difference between this mode and auto, as i haven't driven in auto for the past 9 months, and driving in auto again really threw me off.

And yes, the more green it is the more power it is to the rear, the c.diff roller is just basically roll it back, more power to the rear, roll it forward, more power to the front. I don't know about all the intermediate settings, but 50/50 lock is not a mode to be used on the pavement/street, it was meant to be an off road/dirt/snow mode.

 

hehehe...the title says it all

 

Get a catback or full exhaust then ecu upgrade flash or a management tool as starters for power

 

see youre the first to say i should get a new exhaust. everyone else ive talked to said the 05 sti has an awesome exhauste tuned perfectly for it.. i definaltey agree on an ecu reflash but i cant find one for the 05... any advice where to look... also i jsut bought a blitz blow off vavle did i just waste money???

 

Well i do admit the STI with free exhausts tend to spool the turbo quite dangerously. If you do get an exhaust i will cuation you by say the dreaded words "boost creep"

What is boost creep:
Its when the exhaust keeps spooling the turbo up even when the wastegate is open.

Solution p&p the turbo by a professional shop.

BOV ARE a waste of money unless your running most boost than it can handle say about 19psi. Which i can assure you... your not. Also it tends to decrease performance rather than increase it. If you must get the bov becuase of the cool sound just make sure its not fully atmospheric. the ecu expects a recurculating bov.

Also on the same note dont bother with intakes. Just get a drop in panel filter like green filter.

ECU: the 04 ecu should work for you just fine.

 

is the RFL totally atmospheric? am I losing performance with it on a stock 04 sti?
