Clogged Cat??

Hmmm... weird.

Check the air by pass screw on the top of the throttle body (usually covered by a rubber piece). I still don't think an adjustment of that much would cause it to go up to 7k. Just for caution unhook the throttle cable. Let the butterfly valves just be controlled from inside the engine via your hand. This will automatically rule out the back end of things. Once that's done you may need to pull CEL's to see what codes it's throwing.

LOL, I am still laughing about that.

Check it out, if it is pulling as strong as your NA till 6k, then you have some SERIOUS problems. There should be a HUGE difference starting at about 3k on how hard it pulls when the boost comes on. If you aren't feeling a power surge there at WOT, then you don't have any boost. Next, when the power cuts out, does it feel gradual or does it feel like you just stomped on the brakes. If it feels like you are braking hard for a second, you MAY be hitting fuel cut, which doesn't seem right if you aren't boosting, or you may be running way to rich because you have no boost.

Do this right now, literally as soon as you read this. Hop in your NA, go get the cheapest aftermarket boost gauge you can find, put it on your turbo and go for a spin. Take your vacuum reading at idle and put it in here, then see if it boosts at WOT, if it does, then watch and see what the gauge does at 6k. If you are boosting I expect your boost drops to 0. Also record what psi you boost if it does in fact boost. Put all the information in here and then we can proceed.

Also worth noting, the stock boost gauge is useless. Aftermarket in ANY situation here is the way to go. See what the beast is doing, then come back.

Also if you want to get crazy, disconnect your cat and run DP open for a run or two. That will cross out a few things on the to-do list.

Got a gauge but have yet to hook it up, just got it. Im almost positive its boosting now, i replaced the alt, it was bad, and the fuel pump plug was not all the way together. Also changed oil and added more coolant, fixed a coolant leak and changed 02 sensor and plugs, thats all so far and it feels about 3 times better, i hauled ass down my driveway (its long) it pulled much harder now. Now the only problem is that it floods itself when i cut it off, and it sounds like it has an exhaust leak between the turbo and the engine, i found brand new un open turbo to manifold and manifold to engine gaskets in the spare tire well, along with brand new set of unidentified rear shocks. SOOOOO im doin pretty good. Ill get the gauge hooked up and get back to you tomorrow on all that, i have to get a shower and get to my public speaking class as of now, thanks for all the help guys
