Yet another thread about Turboing a 03 lancer.
So here is hopefully my solution. From what it sounds like most people with my setup are not experiencing this which leads me to one question. Maybe for some reason relocating my battery to the trunk is my problem. I am going to change a couple connections and also I am going to check my voltage to the pump while driving and might add a relay to boost the voltage if needed. I have notice ever since the install my engine turns over a little slower than it used to no doubt due to my relocation and probably some cheap connector somwhere in between.

Thanks senate always appreciate and welcome your input 
. So I just checked voltage at my battery and am getting 13.9-14.1v. However at the pump I am only getting 12-12.5. I am going to install a relay and see what I get.

Ok relay is installed, letting the car relearn idle right now so thought I would post. I am now getting the full 14v and the pump Of course I dont know yet if its going to help although I really hope so I will post results later.

Gotta love the ol' DSM fuel pump rewire trick. I didn't think Lancers suffered from the same issue also. It was probably even easier with your battery located in the trunk. I'm gonna do the rewire to my fuel pump, too, for good measure to increase the amperage draw and get proper fuel pressure now that my pistons and rods were dropped in this weekend.
. Well short answer is yes it helped. I did 3 pulls back to back right before rewiring the pump and was sitting at 12.8-12.9 in my trouble area. Now another three pulls right after with nothing else changed I am getting 12-12.2. Still not enough but will probably pull my injectors and get them tested. I have a max IDC of 71% so definately not maxing anything out.

. As I stated before I just dont know when to quit and since I took a week off work just because I can I figured might as well hit this darn thing hard.
Most likely not, it doesnt seem many people go through this much hassle with afrs. Especially those with the walbro and 440s. IDK what my deal is . As I stated before I just dont know when to quit and since I took a week off work just because I can I figured might as well hit this darn thing hard.

only difference is we have to cut a red wire not a blue/black
Should it be higher?
How do you check your voltage at the fuel pump?

After you pull off your plate covering your pump assembly un clip the wire harness and thereare 3 little clips on that plug itself you will see on the sides. You can lift up on these and the little pastic cover will tilt up exposing the two wires. I just took my voltmeter probes and pushed them down where those wires go in.
I didnt check my voltage at wot just at idle. 13.7 seems plenty good to me.

-4 14.2-15.4V
68 13.9-14.9
140 13.4-14.5
176 13.1-14.5
(idle rpm 800) this is straight from the mitsu diagnostics program at my job
