Hi
Thanks to those who responded to my problem with my power box tuning module.
I took it back to the shop that sold it to me and they installed a wire from
the battery to some grey wire they pulled out of the harness, apparantly it
makes the unit run leaner – smoking is gone now (with a slight reduction in
overall power from when it was smoking), so now I can recommend PSI tuning
boxes for you TDI’ers who want a little more passing power.
