Hey there everyone,
I took my Cossie in to get it rolling roaded to see how much i was pushing before i decide to go to green injectors, chip etc...
I took it to Allen Jefferys down in Plymouth.
Well he got the car to 270bhp but for some reason all the power dropped off around 4.5 to 5 thou revs?
he said it could have been a fuel pump problem but i took it back to him and there seems to be no problem with the pump at all?

is there anyone out there that has had a similar problem like this and what was causing it if you have?

Cheers if anyone can help me out
