    You were using VCM scanner? Does it tell you what to do or did you assume it was the same as LS engines?

    The service information says slowly raise to 4000 rpm. The moving speedometer a pretty...

    Did it do that with the old PCM? have you driven it with the new PCM? If you drive it and the speedometer reads faster than it should you need another pcm.

    Try using an automotive stethoscope but just use the open hose end that is connected to your ears to listen.

    That is not the correct way to voltage drop test. Also, never hook a booster to the fuel control module. You will just fry it if anything.

    You aren't logging cylinder airmass. I don't think you are logging enough to see what is happening. At 3000 rpm exactly Dynamic air dropped a lot.

    Can't do much without knowing what code is setting but i'm sure its front/rear speed mismatch. Hp tuners can't do anything with the ABS module.

    VVE is the set of tables under Airflow-Speed Density-VE Coefficients. You modify it by using the Virtual Volumetric Efficiency Table Editor in HP Tuners under the Edit menu at the top.

    Just setting it back to 4000 should get it back closer to the negatives while driving which is preferable to it adding fuel. They never touched VVE so it should run more like it did before the tune...

    Possibly a vacuum leak or misfire? Use a flammable spray and check everywhere while watching for short term fuel trim to go negative.

    The tune is setup to be MAF only above 2000 rpm and they did not touch VVE/idle. If you want it "perfect" you will need to spend hours doing VVE tuning and also redoing MAF.

    Do you have a fuel pressure gauge? You don't have the factory fuel pressure sensor hooked up. With the factory sensor the pcm will compensate for pressure loss by increasing injector pulse width....

    What is the MAF flow at? A log would be helpful. Oil Temperature based cutoff is enabled but I don't think it has a sensor. Is the engine pretty much stock?

    Lets say you walk into a hotel needing a room. No one is there. You ring ring ring the bell. Someone shows up and says wait a minute ill be right with you. They never come back.

  18. Looking at a stock calibration it is 32.6 psi max...

    Looking at a stock calibration it is 32.6 psi max which for my altitude comes out to be over 18 psi at max manifold air temp. Obviously it won't hit that due to other limiting factors in the tune,...
  19. Yeah, you are totally right but the limitation is...

    Yeah, you are totally right but the limitation is in the size of the compressor wheel and its ability to maintain boost at high RPM. I think most mail order tunes are around 20. Even the ZZP turbo is...
  20. You are very wrong. The turbo simply cannot keep...

    You are very wrong. The turbo simply cannot keep up at high RPM so boost will of course drop. When i'm 22+ psi at 4000 rpm and you are at 17, you think there is no power gain there? That is silly.

    You can compare the calibration that you read from the car to a stock one and make any necessary changes.

    As far as idle is concerned that tune is stock. If its too rich that will make idling difficult. I would set idle rpm to 800-900 or even higher and keep increasing airflow until you can get it...

    Do you know what your AEM fuel pressure regulator was set at? The stock regulator is 48-55 so if it got tuned at 40psi you are now injecting too much fuel.

    Let us know how it goes but I wouldn't put much faith in a shop that doesn't have a backpressure gauge or thermometer. Does it have the 99+ knock sensors and harness? Could it be induced from the...

    Its the startup airflow. You need to mess with the Startup settings under Idle -> Airflow. You have startup airflow Decay at 0 so i'm guessing it won't reduce startup airflow on its own.
