Problem with car!!! need help

[dsmkid95]

well i have a 95 eclipse gst and just got a 1g swap with an evoIII16g turbo and it was running fine the first couple days but on the third day the car started sputtering. from 0-40-45 it was fine but when you went higher than that or run on 4th or 5th gear you start hearing a sputtering noise out the exhaust and if you down shift and go back to 5th, its fine for a while. now could this be because my car isnt tuned yet. i dont have my safc, fuel pump or injectors yet and wont have them for another couple of weeks. can someone help me with this? and my air/fuel gauge is maxed on richness.

Also what size injectors would you recommend me getting with my setup. 550's? or higher? im not planning on boosting anything higher than 18.

well after looking at some of your mods, you dont have a recirculated bov, that may be part of the problem. Also for injectors, i'm running stock 450s with my evoIII b16g, i've boosted to 17 psi daily with no knock on them but i have just about every bolt on and they are actually putting more fuel in then they should. So i would say 550 minimum, 650s would be best so you aren't overworking the injectors on their duty cycles too much. Brandon [VFRacing]
