boost probs....(have catback and dp and intake....stock ecu)...
 

hi guys i'm having some weird problems with my boost......in all gears i don't have much power between 0-3000rpms occasionally i'll get 7-8 psi..but it feels like the car isn't movin nowhere......

1st gear:

weakest of them all....i get a grand total of 8 pounds but it takes until redline to hit that....

2nd gear:

nice boost.....3000-4000 hits 8 then rapid increase to around 14 at 5000-6000 then drops back down to 8 till redline and feels like i'm losing power after i hit that 14....
heard its unsafe to redline with my setup so i don't.......

3rd 4th 5th gear:

same as second....

help me out........i'm in desperate need.

From the sound of it your 2 turbo is not coming on .That's the best I can narrow your problem down .
The second best thing to do is a search on (BOOST PROBLEM)
That will definitely help you out !
Good luck !

hey what's up....thanx for the tip...but how can i find boost problem........u really think my 2nd turbo ain't comin on?.........hmmmmmm.......jeeeeze.....where do i start with checkin it...out...i'm lost...i'm down..i'm out.....help!

Click "search" above right below the red 2nd gen. :)

sounds like a pretty sharp spike up to 14 psi...you'd better watch that too.

if your getting up to 14psi with stock ecu, you have some serious problems. it could be a restricted wastegate or cat. it could be a fuxored secondary turbo.

just remembered there was a post just last week or so, very good post by technovoice on testing your secondary turbine:
