wisp of smoke under boost?

wisp of smoke under boost..... small valve cover leak onto header. stupid, but hard to find.

Well I'm all done and tuned.
Here's what I have...

stock engine
stock cams (adj cam gears, degreed)
AEM ECU
T72 BB turbo
full exh no cats
Dual Supra Pumps
Ross Machine Fuel Rail
850cc injectors
3.5 bar map sensor
GM IAT sensor

18 PSI on pump gas we made 482rwhp, 430tq.
26 PSI on 110oct we made 619 rwhp,560 tq.

We had a lot of trouble setting up the boost controller (HKS EVC IV). We had to use a knob for a controller, because of time constraints. It seems I'm out of turbo. high boost seemed to drop off about 6800-7200, although it seemed to still be making power. Anyway, just wanted to finish up this post as it has been hanging for about 6 months.

BTW, AEM, not so bad to set up. Don't be afraid, it's worth the money and (very little) trouble. Just use a base map for your car and modify it. We had about 6 hours on the Dyno. It looks like I only need a couple minutes of street tuning, as I have a slight lean spot at cruise.

Thanks again for all you help and info
