My car is currently running stage 3 but I think it has a map sensor prob.

If I was to get a 2 bar and stage 1 chip, would my car run with the 803 dark greens still fitted ? and if it will what (if any) downside is there to this, i,e damage over fueling etc.

Reason being noone I know local to me has a 3 bar...

 

Not sure if this is right, but I was always led to belive that the chips are rated to the injectors.

Stu has some 3 bars

 

you can only run yellows/blues or the light greens on a stage1 chip,greens you will need a greens chip

 

thats what I thought, but was worth a try.

I know stu has them, but 1 im not certain it is map sensor prob, so don't really wanna spent that much on the off chance.

If I could get hold of 1 to test with and it sorts the prob then I don't mind.

If that makes sense

 

well you could always send yours up to stu for testing mate
dont think he would charge much to test it
