I was driving down the highway today at around 60mph. When suddenly the truck started to accelerate...ALOT...Like if i'd be full throttle and emptying a bottle of NOS. Within 5-7 second the EGT went up 250 deg F and even engine temperature raised 10 deg F very quickly.

So i let the throttle go for a few second, then apply throttle again. But the thing was like on and off, and pulling like crazy. So i coast to the side of the highway to let the thing cool while i check what is wrong. I don't see anything, so i get back in to get to the next exit. Still, the throttle was on / off and the truck accelerate like i never seen...i mean ALOT. While i'm trying to maintain speed to reach the next exit i though that maybe the waste gate hose disconnected.

So once i'm stop again, i check the hose and it seem ok, but i don't trust the T i installed with the bad connection that came with the boost gage. So i pull it off and find a plug. I try the truck again and same thing. So i start looking around and find that the hose from the throttle body that goes on the fuel pump was disconencted. So i reconnect it and put a tierap. And that was it. What is that house for? Seriously the increase in power is mind blowing (i guess for a turbo engine).

When i removed the T for my boost gage i did a few hundred feet to test it. But i had to turn around, you should have seen the cruiser spin the wheel and lay some good rubber on the tarmac...

Good thing i discovered this before my dyno run ;-) But what is it for?
