Wingless alas. Too bad it took a 50 ton truck to make it happen.
well we just came back from a visit with Harvey, tuning my roommate's stage 2 06 wrx LE. he put down 214whp, 238wtq. his initial stg 2 OTS map pull was 201whp, 205ftlbs. This is at 5000 ft. he gained about 14 whp, and 30ish wtq. so if cobb's site, at sea level, says a stg 2 06 has 285hp, 335ftlbs he gained about 60+crank tq and about 28 crank hp. its very very smooth. boost comes on in a flash, as soon as u hit the gas it leaves forward, almost like a NA v8 feels, torquey. we did a pull from about 25mph (my sti is stg 2, AP map) down low he kept up but the top end just isnt there. thats where the car is lacking, it just runs out of air. i honestly thought a protuned 06 would put up more of a fight, but the turbo is jsut too small. i drove it though and i would highly recommend getting a protune. while his power didnt go up huge, the drivability of the car is awesome. the spool is super fat, power everywhere and the smoothness of the power is awesome to have.
sorry for the jack but i was wondering something. i have a 02 wrx wit a catback,gp moto headers with up pipe,mbc set at 14.5 psi,rs bov,street light flywheel, so i was just wondering what i should be pusing after a tune and what stage im currently at. sorry for the newb question
ok well sorry for the newb question. well i justordered the obd2 cabel and my friend nows how to tune so hopefully i can get the car running better with a tune. but why is the mbc and bov bad for the can not understanding.still new to the car.any help would be great
Ok the MBC is bad because you have effectively increased boost without correcting your AF ratios. Stock Wrx EM has a boost taper at the higher rev ranges. By adding a MBC you dont allow the boost to taper and thus lean out the engine. which inevitably=boom. An MBC however can be a useful tool when used by a pro tuner in helping dial in your mapping, as long as you yourself never touch it.
The type RS BOV is a non recirculating BOV thus it vents 100% to atmosphere. On a MAF metered car this is very bad as the car cannot account for the lost air and creates a rich condition. If you must have a BOV buy one that is a hybrid and recirulates at least 50% to counteract this effect.
In effect your car right now is a manic depressive on crack. It is lean at the top end and rich when shifting.
ohhh ok well thanks now im gona go put back on the stock bov and take off the mbc ill be running much slower but oh well i can wait for a tune. thanks for the info.

You can run a car that is detonating or running lean for 20-50k miles without blowing it up, my buddy is still doing it. Just don't expect any kind of longevity. Especially if you are going to further stress out the engine with mods and upgrades after it has been detonating for 20k miles.
Heres the sheet if anyone was interested. Im just bored.
