A few months ago I had a friends IAW moniitor linked upto it and from memory it didnt show any specific faults with the TPS.

Furthermore I have noticed that I also appear to have an intermittent boost issue. Sometimes it will reach full boost and others times it wont quite make it and tail off. You can certainly fell the difference when it makes full boost to when it doesnt. I'm talking about it only sometimes reaching 16psi and other times reaching 20psi but tailing off.

I've replace amal valve and checked wiring, actuator appears fine (-34), Im sure its not a boost leak but did not now whether this problem was somehow linked with the ISCV issue.
