fg xr6 turbo low boost

[docheb]

Hi, I have an fg xr6 turbo. Long story short...I put an external wastgate on it...didnt work properly...returned back to stock...car feels sluggish. Im a mechanic by trade, but i cant figure out what I've done wrong. It just doesnt seem to have that surge of torque it use to have. Only mods ive got are hdi intercooler and k&n panel air filter. mods were done before external was fitted. Boost gauge is showing about 7-8psi until it reaches operating temp...then about 10psi...but not all the time. Sometimes it only reaches 7-8psi. Im thinkinh it has something to do with my actuator. Any help will be greatly appreciated.

Are you sure the actuator flap is sealing, closing all the way?

yeah...when I put the actuator back on, I had to pull the rod to get over the flapper leaver. It was sealing tightly, but if it comes down to it, ill remove my dump pipe to inspect it.

Exhaust or boost leak??

I put new gaskets in when I put it back to stock....no leaks The T3 flange gasket was actually missing when I pulled it apart to mod for external wastegate, but now has one. Im starting to think that im just use to the power...And theres actually nothing wrong with it. I had the external on my car for a good 5-6 months, and even though the boost was fluctuating...it had better mid to top end torque...and now im starting to think that I was expecting the torque to be the same when I changed it back to stock. Thanks for the ideas guys...ill just have to save some penny's to buy a flash tuner.

Hope it works out, i was thinking exhaust leak, blocked cat, even the solenoid on the turbo might be faulty. I'm sure all cooler piping is tightened?

You put an external gate on without a tune?

ford by design to not put a gasket on the manifold/t3 flange just fyi. I thought the same when i took mine off. Still dont have one in between.

Best thing for you to do is put it on a dyno.
