Cool variable speed turbo unplugged!

I bought my truck with egr deleted, cold air intake, Spartan tuned etc... the check enginecloght was always on and there was a Turbo boost code coming up and the cruise did Not work which had me n several mechanics baffled.... we finally discovered the wires connector on the variable speed turbo was unplugged...plugged it in no more codes ,check engine light is off and cruise works BUT it barely smokes at all and doesnt seem as snappy as before... so my question is Did whoever set the truck up unplug that for a reason??

"BUT it barely smokes" you sound upset about that? I might be wrong but the fact that its not smoking as much is telling me your getting more complete combustion. What was your boost then compared to now?

no , with a 250 tune or better, you should see a 4x4 puff of smoke at WOT....

No, if it was unplugged, it was done by mistake. There is no advantage to having it unplugged. And smoke is bad, its unburned fuel going out the tailpipe. And at nearly $4 a gallon, I would much rather use that fuel to push the truck forward than make a "smoke show". Leave it plugged in and enjoy your now better running truck.
