Running lean

[WayneCivic]

Hey guys
Just after abit of info my friend has a Evo 4 we have just fitted a JSpeed Evo 6 ECU, Evo 6 injectors, Manifold, Turbo elbow, down pipe and a Greddy boost controller.
Took it to get looked at to make sure it was all ok and was told the JSpeed map was rubbish and making the car run lean and needs a remap.
At the moment everyone is busy to remap the car, so was just wondering if he was to put the standard Evo 4 injectors and ECU back on would he be safe to run his car until he can get it remapped with the extra manifold,elbow,down pipe and boost controller?
Many thanks guys and info is greatly received :smthumbup

I wouldn't be changing parts back and forth! I doubt that no one can fit you in?!?!
I'd leave it as it is and don't drive it until it's been mapped or I'd say your next thread would be about building a engine! Or you'd have a wanted thread up.

I'd say what ever you do revert to standard or leave it will need to be looked at....

Stay off boost until it's mapped and you should be fine.
