thanks for the reply. air filters new cone K&N, fuel filter is new (less than 1100 miles), exhaust is 4" strait pipe turbo back (checked it, but no obstructions), smoke is same color, smell as always, the EGTs climb to approx 1000 at take off from a dead stop, under normal accel (empty) and 100-1200 when loaded. I use the truck for towing a 40' flat bed trailer, and it does get "loaded". I was never able to get over 20lbs boost before i installed the fooler, and with it wont get over 24lbs. I have checked the guage for leaks (gaskets too) and have found nothing. I have even disconnected the waste gate actuator and still no gains. Is my turbo bad maybe? Any ideas or suggestions are greatly apprecieated.
I read everywhere the HX35's are good up to 35-40lbs but Im having a hard time understanding why it will not achieve these numbers. It is almost as if the boost builds great until that point then it just stops increasing, as in it hits a wall and the engine is still accelerating for another 1000 rpms or so. Cuts out way to soon. Thanks again guys for the suggestions!!!
