Hi - see you if can help out a newbie.



On my secondary at what seems to be transition I am getting a spike to about 14.5 lbs. WAAAYYY too much for me right now on the stock ecu.



Mods are just a simple K&N drop-in, a punched out precat and a catback. Primary boost is at about 10-11 lbs. Spike is bringing up to about 14 on the secondary.



Question - why am i spiking with those limited mods?

And will a Dawes device help out with the spiking?

What about a popoff valve for either wastegate failure OR for those cold Canadian days??



Thanks.

You running any boost controller? And i would check the wastegate. Just me though, kinda limited on knowledge on that subject.. still learning.

No boost controller at this point. I have been told that boost "controllers" typically only turn boost levels up not down (ie can't help boost creep).



But I keep getting different stories. So now I am looking at Dawes to try and attack the secondary boost spike.



14 lbs is great for drag passes but not for me. I want to try and keep as close to 10 or 11 lbs as possible.



And I have been told that porting the wastegate will help only minimally as well. Porting would however be considered when my current engine blows (whenever that sorry day will be)



Why is it that for every solution there seems to be a conflicting view?



Calling all experts pls!

you need a boost controller!!

You can be ghetto and get the parts from home depot. Not exactly perfect, but it helps.

you can mess around with the pills on the precontrol.

Is there a preference between the Dawes controller or the Home Depot style? Does it make a difference?



And I haven't touched the pills yet but can look at them.

Thanks for the rotor housing.



Go with the Home depot valve, its way cheaper and quick to install. If you need more help PM dont be a rikki

Do a depot valve for now and mess with the precontrol pills, get a larger pill if i'm not mistaken to slow down that 2nd turbo, you can also remove the pill out of the precontrol to see if you can drop the boost..



I think this is correct? i might be wrong, its been a while since i've messed with my boost problems.. don't have those anymore.. .NON SEQUENTIAL !!! ^_^

Yea just get a valve from home depot and put it in the line. You can then dial down the boost.
