So I just installed the AEM truboost and I have no clue how to adjust it.
Right now i have it set at abt 12 psi and something like 6 spring rate on the wastegate.Well i dont kno1 what the stock wastegate is set at so I didnt want to increase the boost just incase something goes wrong.

If someone could enlighten me on the stock wastegate spring rate how exactly to set this thing I would be really greatful. All im looking for is to be back at the stock 19 psi boost setting. thanks

Mods are AEM Truboost and BR Intake

just keep putting the boost duty cycle up until you reach 19psi

the stock wastegate i believe opens around 11psi

set 11.5 spr then raise duty cycle until you hit the psi you want. if you cant seem to hold steady boost (never holds the same max psi value), raise or lower your spr until you hold the highest amount you want.

you really have to toy with the thing. especially in different temperatures. in winter i set to everything to hold 23 psi but in summer it only hits 21 psi. so i have to adjust duty cycle for each season (i switched between a and b settings). your car, turbo, and altitude even play a role. using someones values can get you a general idea, but you really need to adjust it yourself to find the correct values.

a quick suggestion, always use lower duty cycle values than what someone suggests because 52 on someones car may give them 23 psi, but on your car it could give 25.

i just hooked up my true boost. i believe my spring is set at 11.4 psi and duty cycle at 30. my psi on cold nights will hit 23 psi and warm days 20 psi. it took a little but you just have to play with it.
