Guys, I'm driving a persona iafm 4AT.

installed Arospeed fuel pressure regulator few weeks ago and the setting is at 2.8bar (~40psi). after i read up, i found out that the standard pressure setting shud b around 3.5bar or so. just wanna know, at this low pressure 2.8bar, will it cause transmission lag issue? cz im facing transmission lag issue. it is like transmission slipping when gear upshifting.

first time using FPR so no experience in it.:help:

But the FPR is on fuel? Not related to tranny also
tats y...just wanna know..cz found an article that states this

"Transmissions and incorrect fuel filter diagnosis

People sometimes misinterpret symptoms of a fuel filter problem as a transmission problem. Lowered fuel pressure, from a restricted filter, may cause the transmission to shift erratically or not at all. Drivers often incorrectly diagnose pressing the accelerator without the vehicle increasing speed, as a transmission issue. They have needlessly replaced transmissions because of mistakes in diagnosing the actual cause. Driving the vehicle under a load, while testing fuel pressure, will help to eliminate mistakes of this nature."
