Engine/Transmission (1998.5 - 2002) HX40 high egts wont build boost

[BBain]

Afraid I have to much turbo and not enough fuel. Have factory sticks and VP44. The highest psi I can get is 25 with the wastgate shut off and the adrenaline on level 10 the HX40 has a 16cm exhaust housing. When accelorating the egts run up to 1200 and stop and then when I let out of it and cruise about 60 or 70 on the Hwy the drop fast and sit at around 750-800 pre turbo. Then if I hit a slight grade and the cruise puts alittle fuel to it the egts run right back up quick. This is empty no trailer.

Is a 200 hp injector to much for an HX40 or should I go with 150 hp?

Check your intercooler hoses first for leaks or damage.
and double check your waste gate.

Thats All i can add

Thanks already checked them. It just doesn't seem like it has enough to spin it. It's like it just cant quit get the turbo light. I drove to work today with the box set on level 10 and it drove pretty good egts didnt get to bad rode around 750-800 like before and didnt get much higher unless I really mash on it and then they go up to 1000/1200 quick but they seem to stop there and the boost hit between 20-25 psi.

I have 90hp injectors and a HX40. The waste gate is set for 35psi and its very easy to hit that mark. With the J/A set on#2 I can see 26-28psi. Anything more and its fully lit. I think you need some bigger injectors IMO.

I have an HX40 and can open the wastegate with the comp turned off... something is amiss with your setup.
