03 evo running lean.
OK guys im have a problem with my car. Its an 03 evo 8. when wot the car runs lean and breaks up. Ive tried a new maf and that didn't do the trick. I put new plugs also. Also the guy who owned the car before me did the fuel pump himself and when he did it he broke four of the studs that hold that fuel pump and is not sealed would that have something to do with it?the car has got some stuff done to it.

If it is consistantly lean I would stop doing WOT pulls to start off. Get yourself a wideband that can log, a tactrix cable and Evoscan. Richen up the maps a little bit where needed. Unless you are saying that the lean condition has started because of a mod you recently put on. Then you need to find the cause of the problem directly.
I would drill and tap those studs out for the fuel pump. Make sure you have it secured in there, don't want anything falling into the tank or fumes escaping...
