i recently put a catless dp on my 07 wrx. i now have tbe with the cobb ap. i flashed to stage 2 and i didnt feel right. thought that it would just take a while befor it would really kick in. after reading further i think it might be fuel cut. between 3 -5 gears when it hits about 3to 4000 rpm it just kinda bogs out it wants to go but it just wont. what do you guys think. if it is fuel cut what can i do about it as fast as possible beacuase i heard that is not good for your motor. what do i do

i thank everyone for their support on this problem

 

if you have the dough, go get tuned.

if you don't have the dough, sell your catless and go catted.

i just went stage 2 recently, boost creep like crazy with my perrin catless. traded for a helix catted and now no boost creep.

it won't hurt anything as long as you don't hit the cut. for a week or so i drove like a granny. you can pretty much punch it in 1st and 2nd, that's plenty to get you ahead on city streets. on the freeway though, don't try to pass up cars.

 

Doesn't sound like fuel cut or w/e. It's usually accompanied by a harsh 'jolt' to your car, followed by CEL and you won't be able to accelerate for a couple seconds.

Maybe just a loss of power in that range?

 

i dont have the cash to get it tuned yet and i dont have enough money get go catted either i will post a thread to see if anyone wants to trade +i will ad cash but i think im going to put my stock dp back on or something. so its boost spike that is doing this lto my car??? or was it a fuel cut.

 

no jolt and no cel it happend as soon as i put my catless dp on

 

get tuned go to gst

 

well i have a vf43 brand new just waiting to jump in my car but i dont have the money to get it put in and get it tuned.

i think i was going to go with db tuned because its right down the street and i trust pauls advise and what not

 

do that then

 

i have an 05 with only the uppipe cat....im pretty sure thats what happened to me last night.....but it was in 6th gear

 

You can easily install a turbo with a friend, and either look on cobb's forums or email tech support about getting you a vf43 map for a stg.2 '07 WRX and you'll be fine.

Characteristics of the small 13T turbo you have is fast spool, but they drop off fast. I'm guessing that's what's happening to you. I highly doubt your car bogs down while driving WOT 3-5th gears.

How do you have a cat. in your uppipe??

 

thats whats happening it the power just stops your rpms go up very very slow its like its not getting fuel or something

 

its definitely not fuel cut... do u have any vacuum leaks that u know of?

 

does your car jerk like crazy, followed by your cruise light blinking?

 

or a CEL!!

 

I doubt it's running so lean that it's slowing down. It's hard to diagnose it like this without seeing it. Maybe you're only running wastegate pressure (7-8psi)? I'm not sure.

You guys really need to read the thread better. Just a few posts above yours...
