Vr4 help?

[TurboVr4ME]

im new to the DSM scene. i recently acquired a 91 galant vr4 with a bunch of mods that i already forgot. it came with a air fuel psi regulator and i was wondering if anyone knew how to replace it. ive done some research, and it sounds like a quick bolt on but i want to make sure. the car has a boost gauge and a air fuel ratio gauge. when i drive the car it is more on the rich side 'lights up red' do you think that the replacement of the FPR will enhance performance while fixing this issue? One more thing. How do i know if my car is a 1 g or 2 g or is that just in the talon/clips?

With out a list of mods its hard to tell you what needs to be done. What is the air to fuel ratio in numbers? Sounds more like it needs to be tuned to me. What pis is the fuel regulator set at?

i know it has aftermarket injectors. it goes into the 14ish on the guage

yeah i did some reading and i know that i have a 1g :/ thank god.

they might be 720cc if i remember correctly. they person i bought it from gave me a mallory fpr with a VDO gauge and said i needed to install it.

What are you using to control the injectors? DSM link SAFC or something else?

That's a big step coming from a regular toyota truck to a modded Vr4. Is there any way you can get a mod list from the previous owner?
