my 97 v8 esprit has a bad attitude.
I AM OVERBOOSTING
I am trying to dial in 15psi all internals heads ect have been modified to handle.
I replaced the capsuls (10psi) they start to move when i apply approx 8psi w/ a mini hand pump.
all hoses are good. I installed a manuall boost controller which seems to have NO affect either way????????
I have the controller after the stock boost sending unit in the engine bay on the back firewall.
The vacume line comes from the throttle body into the ECU compartment into a (?????? Valve) then into the sensing unit on the firewall, then through my controller to the turbos. correct?
If the vacume lines are good & I can pop off the capsulls with a hand pump at 8psi.
What the heck is causing me to overboost........full boost at 1/4 throttle?
Accepting all opinions no matter how crazy they sound.
