How do you remove the overspeed beeper?

9 - 10 ( max ) psi ..

Page EM-35 of the FSM states that turbocharging pressure should be between 6.0-8.0 psi, or 41-55 kPa.

Having said that, before I shimmed my wastegate, my max pressure was only 5.5 psi. Now it's making 9 psi, which has added a considerable amount of power and very noticable decrease in black smoke at hard acceleration.

So it means that is safe shimmed my wastegate in my stock 1HD-T . ?

David: Gbusch has a BJ74, which of course is a 13B-T...which was what I was referring to. I don't know about your 1HD-T.

David,
you should be running 14 psi already in the HDT so unless you really need more power then just leave it alone...
KISS principal...
cheers

OK .. letme be clear .. and well underestand.

My 1HD-T factory makes 14 . psi .. ?

Well .. really I don't need more power .. but you know .. Always you want more .. I'm still thinking in a intercooler.

the 2 HDT i put gauges on was producing 14psi stock settings...

that's a great notice .. ! so .. the 1HD-T can handle more boost . ?
