You mean a line off the boost source to the fuel pressure regulator? You can t into pretty much any line that doesn't see vacuum...I have mine run off of the coldside hard pipe

yea i know that but what does the bc need to have a line tapped into the fuel reg for??

It doesn't...unless you want to tap into that line for your boost source for your regulator

im srry, call me an idiot but what would it do for the regulator?? i remember in the instructions it said to do but i never did.

The return line uses a rising rate fuel pressure regulator...when you hook it to a boost source it will increase fuel pressure as the boost pressure increases. It is usually a 1:1 ratio

I'll try to find a better explanation of how it works...I don't really know how to explain it clearly

I recruited some more help from a few that can explain a little better...

This could help you out in that regard...what are you tuning your fuel with?

fuel mods are an agp return line (60psi), 255 walbro, stock injectors, i dont have a dtec yet and still have stg 0 (stg 1 on the way) so i've gotta mapclamp

That is the problem with the mapclamp...you don't have the ability to tune as the rpms change. It only allows you to set the map voltage at 1 setting.

I bet getting the dtec will solve your most of your problems with the irregular afrs though

I have only messed with my car, and I never played with anything (fuel/boost) when it was stock, I went from stock w/ exhaust & intercooler to big turbo

I wish I could help you out more. If I were you I wouldn't mess with it to much if it is safe, I would wait on the dtec
