I know it's been done to death but im getting amber lights between 7-8k revs
it was flashing red but i have upped the fuel pressure a bar and it's a lot better, would it be the MAF?
The car is a built 2.33 engine mapped to 1.3bar ( dont know who mapped it)

 

Come on guys somebody must have a good idea what the cause of this could be there are so many experts on here, where are they when you need them?
