No. It is your tune!

If the solenoid is ticking then it's being triggered. Which means the fault isn't the solenoid. The solenoid can't just power up all by it's self without it being told to switch on and off.

In case you missed it in this thread and the other one you started today... It's the tune.

When you load the tune if the tune has allowed you any freedom in adjustment,

it should come up with a option of letting you choose if you want to just load it or adjust it.

from there it will be the first option and you just adjust it to 100%.

I have my car apart at present so if anyone could give this guy a step by step

with the exact options displayed on the Xcal2 it may help him.

Agreed. It's the tune. It's the wastegate dyno duty cycle value that has been farked with to get boost up, rather than doing it the proper method using the desired boost and wastegate duty cycle tables. Your boost is probably running in open loop mode as well, meaning there's no error correction for changes in charge temps etc.

This problem is SOOOO 2005 ish :lol:

I have done this mod at 3 different times now and did not feel any difference on all 3 attempts. The throttle body clean fixed my rough idle though.
