have you checked your wastegate actuator?? Many go bad, when the diaphragm in them tears it creates a leak and causes all sorts of boost level problems and generally usually starts to run like s***.

To find the wastegate actuator, follow the vac line that (at least in a stock setup), tees in with the line that goes to the BPV. Pull the line off of the tee, and blow into it.... if air escapes through, its gone bad, if no air goes through, it should still be fine.

Thats the first place i would start.

Are Wga Easy To Put On I Never Done It Before And What Wga Would Someone Recomnend And Is It Easyer To Have A Ajustable Or Non Ajustable Wga

i believe its the ATP wastegate actuator that i bought to install.

I know that *************.com has the correct replacement....

now, with these replacements, they fit and they are 6 psi actuators, however some people will say that they are not as good because the stock piece is actually adjustable while the replacements are not.... but i believe its more of an issue of $60-70 for the forge replacement vs a whole lot more ($280 if i recall correctly) for the OEM piece.

The install is only difficult due to the awkward locations of some of the screws. Its just 2 screws and a clip, but it took me at least an hour i believe, and that was with help from my dad. A ratchet flex joint should help out alot, as could some long pliers or a long screwdriver.

The ATP is 6psi and teh most economical, plus they last! The 6spi is only for the minimum though. You'll see more like 7-8 with it on the car. Install isn't too bad, just takes some patience, like jmv said it is an akward position. I have been running my ATP at 10psi for almost two years. Here is the one you want: ATP WGA

 

[patty AT forge]

Our actuator (Forge) retails for $150, its adjustable, can be built to hold between 5-24 psi, and has a lifetime warranty.

I don't think you guy's give this motor enough credit I had been spiking 19 for three years on a bad wga and mine is still together.

 

[mikeski]

i boosted to 10psi before and always hit fuel cut. im staying around 8-9 range.

You are maybe .01% of the population and are sooo lucky! Just a matter of time!

WGA isnt hard to change.. you can do it while its on the car.. you can go up from the bottom and remove the c-clip.. hardest part is getting to both the nuts that hold the WGA to the bracket.. might want and extra hand putting it back on if you do it this way.. makes it alot easier..

for what its worth.. i prefer adjustable..

the forge is only $135, not $280 http://siteground207.com/~protegeg/product_info.php?cPath=281_32_181&products_id=1095

my bad, i was remembering things wrong when i typed that... i was trying to compare ATP ($60) to OEM (alot more, but i can't recall exactly how much.... i believe significantly more than the also adjustable Forge unit).
