I dont know about speed wise(mph reading), but it usally happens when the foot goes to the floor, it happens a sec or two after that.
I think you have a massive boost leak or exhaust leak. Is your mileage very poor?

My turbo is working all the time,,,,,,,,,. Anyhow, mine seems to really get going at around 2000rpm's. If you're not used to a turbo engine, they will do more when the engine rev's up. In other words, at 2000rpm's, you will have more boost than 1000rpm's. The more boost, the more power. I heard Gale Banks say that a diesel engine will gain 7% in horsepower for every 1 pound of boost pressure. There is always a little bit of lag time from when you hit the pedal and when the engine catches up with your foot.

Is it safe to assume you still have the stock turbo in there? IIRC, that took a little bit to get lit, but not much. 35mph . . . that makes me think leaks. The one I have now, it spins almost all the time. Pretty much any time not just idling, and it spools fast. It'll go nothing to pegged in about a second on the gauge, and even though its different, its not THAT different.
Do you have gauges or are you judging by ear?

What can you tell us about your truck? What year? What engine? How many miles? An exhaust leak around the turbo where the exhaust comes in to the turbo will cause them to not work properly. Also, a leak in the air induction system will cause them to not work right too. Are the bearings possibly going out in the turbo? Look for signs of oil between the turbo and the air to air cooler, and the exhaust.

I just put my gauges in and this is my first PSD. Depending on how much throttle I give it I see 2 at little throttle and 18 when I stand on it. As far as whistle goes I have a loud whistle as soon as I give it a little throttle.
