try getting it all set up mate

 

It should feel massively different, especially torque wise.
I suspect there may be a problem with the car to start with before the conversion.
Usuall things to look at are the voltage at the fuel pump under load, how old is the fuel filter ?
If it has not had one a fuel pump rewire is going to help resist meltdowns, and is a must, as well as the fan rewire.

I'd get it serviced and set up m8.

 

il bet your actuator is set at 8psi

do you have a boost gauge?

 

did you pre load the actuator rod?
or have you even adjusted it?

 

Hi thanks for the replys i have adjusted the actuator nearly fully in could it be that it needs to be remaped?
