Yeah, the reason why I bought impact wrench and other tools and do not let some dumb ass to touch my car anymore.. Fix that VTCS - you cannot tune the car with 50% of intake runners closed all the time.

Where do you connect for boost leak test? What do you use as air source and what pressure were you able to build during test? Compression/leak tests? What map do you run? On second look, I'd put my money on what looks like disconnected wastegate.. WTF??!! That car REALLY needs good inspection...

Does anyone make shorter cables for AP? I really hate the size and weight of that coil hanging..

Keeping EGR off also makes IM pulling much easier. You can borrow the scope from HF. How many mpg do you really miss? On average (25 mpg, 15k yearly, $2.50 pump), every 1 mpg equals $50-$55 per year.

@Redline - if there was initial build-up from pre-meth years, then I doubt meth injection will do much or anything good. May be just open it up and check yourself? It's not that hard really.

Something similar happened to me once too, rear caliper. One pad worn down to metal while other was at 90% Root cause: sticking sliders. My guess is that shop used grease that made slider's rubber sleeve to expand.

If you're asking me, then I used Mirka abralon pads (500/1000/2000) and Spray Max 2k Glamour High Gloss Clear coat (part USC-3680061)

Couple weeks I've cleaned my intake valves, after ~60k miles from previous cleaning. Had EGR delete and OCC for all these 60k, but I think my old OCC sucked. Now I got DIY one, 5 good lbs of brass and copper and switched to CorkSport "check valve less" routing. Will keep an eye on this sucker...

Let me brag about my work.. Not Meguiar's kit, but still.. Before, in process and after. Will see how they hold under Colorado UV levels.

Yeah, it's true, exhaust manifold can reach 650 C, glowing dark red. But downpipe is colder and it's over a couple layers of fiberglass wrap, so I think it will hold up.

Ohmmeter

From mighty Google.. Common Misdiagnoses Throttle or Pedal Position Sensor is replaced when the real problem is a poor connection or chafed wiring

Trailer park style heatshielding..

There are some of them that do not have rear metal bracket and they sag badly. RockAuto sells the good ones, same as oem.

Yep, now I figured that out! Thanks for keeping up with me! Btw that's the article that I found useful: http://blog.perrinperformance.com/boost-control-systems-explained/

So, at zero WGDC (or completely open wastegate) all exhaust gases are passed through wastegate without giving any energy to the turbo to add the airflow. Correct?

I think you lost me completely.. Seriously, with WDGC = 0, what is the magic holy power charging compressor and "adding airflow"?

Ok, correct me where I'm wrong, please. Assuming that we define "turbo is adding airflow" not by ear, but by when wastegate duty is >0. Intake manifold running on vacuum and turbo building the boost simultaneously - this is the scenario when BPV opens and air will just recirculate. Correct? So...

So, again, how exactly do you know that "turbo is adding airflow"?
