Should I disconnect my stock increase control solenoid?

I am using an hks evc to control increase and have been for many years.The car is pretty changed vf 22 turbo,550cc inj.,up pipe,turbo back exhaust,utec engine management,intake,front mount intercooler.

HKS increase control is" T ed" into the stock increase control to the wastegate. Everything is working properly and you want to change something that isn't broken? Most of the time the increase control motor either bleed pressure off of the wastegate allowing more increase. Or expensive HKS digital units replace the stock increase control totally. Kaboom. means to much increase and lots of white exhaust smoke

You do and that is the end of that engine.

again you sound like a complete moron don't screw with anything unless you're properly trained to do so and I doubt you're. go back to your import tuning magazines and leave well enough alone ps im sure with all the mods on your car you didn't do one second of work on it not to talk about your trade in value goes down not up when you start dicking with it again all flash and no skill you could be better off practicing how to wreck an engine on a go kart im sure there's a club for that don't TOUCH...
