I just installed a aem wideband and a aem tru boost gauge but now my Ty runs slower and boost doesn't go past like 6 psi

Did I do something wrong???

How did you set it up?
internal wastegate or external
wdc
sensor

zip tie the hose on back of gauge.

Internal wastegate I hooked it up right I kinda got the hang of it just does anyone know what a good spring rate to have it set up at??

Re: Aem tru boost help

Stock wastgate? Hoses hooked up correctly? Aem truboost sensor setting set to internal or I setting? Is the truboost on? Stock turbo? What's the wastgate duty cycle set at? Spring pressure should be 3 psi lower than wastgate spring pressure....imho...ask me how I know...best way to dial it in is have someone drive the truck while you fool with the settings....
 

It's just a six

As long as you follow the video links, it should work as advertised.

I adjusted my spring setting w/in 1 psi of base boost pressure & works good. But will vary from engine to engine, different wastegate set-ups etc.
When the spring pressure setting is too close to your wastegates base boost pressure,, you will see the boost pressure rise & fall & not be consistent, just like the vid show.

I think the car in the vid has a base boost pressure of 8.7-9.0 psi? They adjust the spring rate to 10 PSI, 1 psi over base boost pressure & it began to oscillate. https://www.youtube.com/watch?v=aDzx2oW0cak&index=48&list=FLC47WILAMLZIhl7pE8DUelg

Good luck!

Agreed....it's gonna take some fiddling with it to get it on key...If you ever need a new solenoid for it they are made by mac...don't fall for the aem bs and pay $100...just let me k ow and I'll guide you to the right solenoid...good luck
