Hey everyone. I had two issues show up almost at the same time, so they might be related.

I have an auto tranny, mk3, 550's, lex, walbro, fpr, 50 trim, running 16 psi with supporting mods.

Auto tranny shims 1/2, 2/3 accumulaters, 12x12 tranny oil cooler with fan

Issue 1: From first into 2nd gear, i feel a consistent vibration (2 to 3 vibrations) slight, as the car shifts from first to second. Once in gear, it immediately goes away. It is not present under WOT in any gear, just in the shifting 1/2 gear.

It happens under 13 psi (boost controller off), and at 16 psi.

Issue 2: On release of any moderate to heavy throttle, I smell a faint oil/metallic smell as I'm driving. This is happening recently. A buddy said that it could be the PCV.

Any feedback or leads are welcome here.

My build thread/mod list can be found here if anyone is interested further: http://www.supramania.com/forums/showthread.php?t=98571

Thanks in advance.
