    07 speed 3 idles all day long will rev up with 1/8th throttle any thing more bogs. Checked for boost leaks, new maf, cleaned hpfp.

    Got any logs? Could be the primary oxygen sensor. Maf sensor is best oem, aftermarket is well known to suck

    This is the only weird thing I can find this is with the car not running seems to not be bleeding off fuel pressure [​IMG]

    Does it follow the commanded pressure when running? The high pressure side has no regulator to bleed the pressure off, either the PRV opens(around 2k psi) or the injectors use the fuel.

    Do the KOEO test to determine if the relief valve is starting to go bad.

    I had a very similar issue when one of my ground straps on one of my spark plugs broke off.

    Check plugs.

    Have you checked the connector at your TB? Does it still have the red tab? Usually that red tab breaks off and the plug gets poor connection from not seating completely.

    Are you sure you dont have a boost leak in your charge piping?

    What are your mods? You should start with an introduction of what's done to the car. Maybe donate? Access metal side of the site that has much more to offer. Post your setup in the new member section?

    This whole thread is useless without knowing what's done to the car or if it's even tuned.

    What does your boost leak check process consist of?

    You gotta spill it all out man. At this point, it could be your tune.

    More input!

    Well fully modified, no tune, that's the problem. Did the hpfp get upgraded?
