hmmm what is your injector scaling for those WRX injectors? the base lancer is high impedance?

Correct the wrx injectors are a drop in affair. I have them scaled at 390 currently

You dont have a bad FPR or line off somewhere? 390-406 should be pretty good, but you seem to be having 2 distinct issues.

1- have to lean it way out during spool

2- have to go to max rich after spool

I wouldnt play with the MAF scaling at all (I never do in fact) as this could be causing some of the issues to be more prevalent. What MAF is on the car? I found on the one Lancer we did that the stock MAF ran out really fast. MAF placement was also critical in keeping it happy.

^That is true, FPR might be the cause. Just like the X's.

Did your fuel pump go in with the install kit?

I have the evo 399 maf installed in my car. I also wonder why this is the case with the spoolup and post spool. I had it set to completely stock evo settings since I have a complete stock evo intake setup (intake pipe, turbo, licp, fmic, uicp, bov, recirc pipe) Then I changed the maf scaling so it would peak where my peak torque and lean issues seem to be at in the rpm range here is my setup since I cant seem to just upload my rom

No I was able to put it in with no install kit but that also means I reused the stock strainer. This is at the same psi my stock maf gave me the exact same lean amounts in the exact same rpm range

The pump sat in tight and is unable to move then?

Correct I just pulled it back out last night and cleaned the strainer which seemed fine to me but will probably replace to be safe and elimanate one possibility.

The O-ring and collar are on top of the fuel pump though? Apparently just not the rubber isolator at the bottom. I havent pulled a Lancer pump housing, I assumed it would be the same as an Evo.

Correct rubber isolator in bottom and rubber seal in top. Do you think I migh be losing pressure? My idc is reading 69% max.

just trying to eliminate possibilities

I have a fuel pressure tester I will check the pressure to see if the fpr is going bad but thinking this. Is not the case.

Ok so I havent done the FP test yet BUT, I have stumbled across something that hopefully will allow me to fix this. So on my car WOT registers at 93.33% (its the same value my obd scanner gives me as well) now every single pull in 3rd or any other gear for that matter that has a full 93.33 in the tps gives me the lean condition. However every single pull I do that has the tps even dropped to 92.94 or lower sporatically throughout the pull the highest afr I get is 11.7 in the same rpm range?? This is probably my maf scaling being wayyy off huh? hope any thoughts on this?

Ok so here is my maf scalings, top left is my stock car stock maf settings (original), bottom left is my maf scaling I made after I turboed the car and still had my stock maf, Top right is the stock scaling for a 03 evo, botom right is my scaling I made for my car with the evo maf, I started using the graph function with the last maf scaling and tried to follow the evo setup except for allowing the max to be hit right where my lean conditions were happening which obviously has not helped me yet any ideas from the pros on maf scaling would be awesome!!! , also so I only hit a max of about 950hz so can/should I change my maf table to reflect a high of 1000hz or no?
