1999 F250 turbo problem

when i start my truck and after it idles for a little bit it almost sounds like the waste gate sticks open or something. the exause gets louder. when i drive it down the road, and barely hit the gas, it will do it too and it seems like it has less power. then after i hit the gas a little harder it clears up. could this b a boost pressure problem. any suggestions on what the problem might b

that just sounds like your exhaust back pressure valve, it just restricts the exhaust to warm up the engine faster

do u have aftermarket exhaust on it, it is much more noticable when you dont have a muffler

i bought the truck as it sits. 10in lift, 40in tires and a chip. not sure what brand on the chip. i think it might be a superchip. just straight pipe about half way back on the truck. no muffler. my concern was it used to do it when it was cold and when i just started it up. now it does it when i am going down the road after it is warm.

Its the exhaust back preasure valve. unplug it. Its a 2 wire plugin on the underside of your turbo compressor housing. mines been disconected for over a year now. I hated that annoying thing.

its for emisions and engine temps so on and so forth... all it really does iss kill your milage and performance and annoys the pizz out of you.
