Waste Gate VS Boost

I disconnected the wastegate and capped off both the red line and the inlet. MPG jumped up by about 4 mpg. Is this for real or am I not seeing something? I don't have a boost guage so just keep the RPM under 2500. Everything is stock on this '99 PSD F250 Crewcab with the 6 speed manual tranny. Am I safe by keeping RPM under 2500 or do I need a guage?
Thanks,
Randy

I would think 4 mph is pretty high just from pulling your red line. You shouldn't have to worry about overboosting, the wastegate will still open, just not as soon as it would with the red line connected.

i tried it on mine a few months ago, no gauges though.
i actually thought the power was the same if not maybe a little less and the mileage stayed the same so i put it back on for now.
bone stock 96psd.
maybe more power if i added a chip but not stock on mine.

Sounds a little better than the one I just installed Bullydog =stock, 50, 75, 100
I hope you have better luck than I'm having. I keep getting a service engine soon light on after about 30mi of driving.......

Ok, so I've read this thread and the above referenced thread mentioned by PSDPOWER. I'd like to ask this qestion, though slightly off topic. I have a '97 which does not have a wastegate, we've determined. Its an automatic. If I take off from a light rather hard, but not floored, when it shifts to third (overdrive off), it feels like I loose my boost and sounds like it too. I don't have gauges yet, but the truck lags suddenly, loses momentum, and I hear a psssshhhhhhhttt sound (like that technical term?) that sounds like all the air has been released from a tire or something. I always assumed it was the wastegate. If I don't have one, is there something else that could possibly be going on?

Kinda hard to diagnose sounds over the internet. If you can get a boost gauge just to hook up temporarily it would be obvious if it were a boost issue or something else.
