Ok installed the Power Fc and ground wires.... now the hesitation is gone but i reved my car to 4000rpms and got only 2.2 psi of boost... can it be that some vaccum is off or may be a clogged cat? Cuz now the hesitation is gone... Before anything near positive manifold pressure caused the car to die... before the car did not at all take abrubt acceleration and started to stall whenever i WOT the car... Now that problem is gone... the mechanic did check the vaccums for leaks before maybe some vacuum was left open... the boost build up is very slow too... What can it be??



Vaccums

Cat

or

Turbos



Thanks guys for all your help

do you have the boost settings set up correctly? also make sure that the option for sequential turbos is turned on

Ok very new to the Power Fc and manual in japanese... where is the option to check sequential turbos r on, on the power fc?

Ok the sequential function is on... can it be the cat then?? or vaccums?
