Running lean is there an easy fix I cant get a fuel pump yet...

[SRiz]

Ever since i got my supra SMIC ive been running lean... is there a way to restrict the air untill I get my pump... like that little screw thing on the intake MAFT

First thing to do is rewire the pump. http://www.raktron.com/fuel/rewire1.html

If it is still lean, turn down the boost till you can get your supporting mods.

Edit: Why do you think you are running lean? I just looked at your profile and dont see enough mods for it to run lean or even any monitoring device to tell you it is running lean

He could have looked at his plugs.

I dont trust that method on my car. Mine are white but wideband shows 11.9 afr and no knock on my logger.

Did you look at them after letting it idle for a little? Every DSM I've seen runs lean at idle so if you pull the plugs after it's been idling they will be white. Do a hard pul and immediately shut it off and coast to a stop. I guarantee they won't be white then.

Plugs don't lie. I know many people with sub 10 second cars that really know how to read plugs and they use them as their main source of tuning. A couple guy's from various shops and a bunch of my teahers at UTI.

I ran it the 1/4 mile, shut it down at the end, and pulled the plug befor making the trip up the return road. I know what you are saying and be no means am I a rookie at mechanics or tuning. I just see different plug coloring on my car than I have on any others.

yeah plugs are white...all of them dunno about after hard pull... I have the wastgate directly hooked up to the compressor so its at like 11psi which is as low as T25 will go I think and I still feel sluggish...compression is perfect everything seems to check out the only thing else that does run well is the idle drops to like 350 after high RPMs and goes back up to 500 but thats cause of a dirty thorttle body... it only started after i got supra SMIC and if I hold like 4-5k rpms for a while ill get a mutilple cylinder misfire CEL...
