Hi all,

When I first fitted my Turbo with a 4x4 housing the car seemed to pull really good. But now the turbo seems to be really laggy and hardly seems to be pulling at all. I have had to put the standard ECU due to my other one being faulty so am limited to 10psi. With the bigger housing on and the standard ECU should it still be pulling away as at the minute it feels really flat or is this because it need more boost to use the full potential of the Turbo?

I am thinking about replacing the atuator to see if this is the cause but if anyone has got any ideas it would be a great help.

Cheers
Dave
