Boost Issue Yes Another

[KurtAss]

Ok so i have full 3inch exhaust, turbosmart manual boost controller, fmic, auto meter liquid filled boost guage and splitfire coils. i have my boost T going from actuator to fmic plumbed into the bottom pipe of the 2 intercooler pipes. The other pipe that goes to plumbback pipe is blocked off.

My question is that my boost keeps changing ranging from as low as 5 psi up to 11 psi i would like it to stay around 10 psi dont mind little creep. i have done the tuning thing with my boost guage and set it to 10 psi and then later on it will change and change through out the day. Im not sure what it is because if it is set up properly my boost should hold 10 psi all the time right? doesnt matter about if its cold or hot because the same amount of air is being pressurised and bleed off right?

and im not talking about spiking and then setteling like bleed valves do somtimes, its when i hold my foot down that i take my boost reading.

Any ideas and help would be much appreciated

cheers Kurt

"i have my boost T going from actuator to fmic plumbed into the bottom pipe of the 2 intercooler pipes" man wtf does that mean ? re read it yourself

are you tryin to say the boost tap is plumbed in a line from the ic pipe to the actuator ?

what car is it ? what turbo ?

have you removed the factory solenoid?

sorry my bad got my words mixed up so i have my boost t in between the wastgate actuator and is then plumbed into my intake intercooler pipe from the turbo... the bottom one, i have the factory solonoid just sitting their with no pipes but still has electrics connected.

cheers

I also had this exact problem with a manual turbosmart controller. I never ended up fixing it unfortunately I just went back to the stock solenoid with the permanent high boost mode and due to the fmic it constantly sits on about 9psi with no realll hesitation like I did with the manual controller. Maybe give that a go if u can't ever figure it out?
