Throttle body
well the fuel system is under pressure thats why we hook into the hose running from the FPR ....are there any check valves in that area? the 180 and 225 setup is a little different so i'm no expert on that motor but if there are any check valves there get them replaced

end of manifold and attachs to the throttle body hose, it alsohas the vacumm hose coming out of it.

as far as diverter goes, there are different spring tensions. make sure you have the right one for your boost level. but i think what is happeneing is that you are loosing the drivability at part throttle. my turbo does the same thing sometimes. If i holdi t at part throttle it will kick in and out as if i'm asking it to boost then depressurize. when i'm only driving part throttle. I think it has to do with the changes in the software and the replacing of the turbo. I would get a boost guage and see if the car holds good vacum , and if it boosts up high enough when you are gunning it. the gt2x setup should kick in farely fast and maintainboost for a while without pressure drop. i know there is a way to spot hose leaks with some sort of smoke that when you start the car and rev it up you are supposed to see where its coming from. good luck, hope you find the answer, but remember that it might be the stock sensors acting funny to fast changes in pressure.
Well the bailey diverter only comes with the one piece already inside and you cant change it out. The piece inside isnt rubber so it wont tear but Im wondering if it is opening to early or late now cuz of the extra pressure. I guess I might have to change to one that does have the different springs. And of course I am going to get the pressure checked and find that leak. But my turbo does exactly like precesion tt says when Im at part throttle so Im guessing thats kinda normal but that is when the diverter valve kinda flutters too. I have hooked a boost guage up and couldnt get past 19 psi, which Im sure is caused by the leak. Thanks for all the help from everyone.



Now that would be bad!!
