Mine has a Precision 7675 with WG dumped to the atmosphere, and it's pretty loud when it opens up.

It was checked after the fact with zero issues.curious to know if you, did a compression and leak down test on the car before you bought the car? Also If you are in the 9's at wot you could be cylinder washing which isn't good.
plenty of people end up with numbers in that area with a TS at the same boost on pump gas. You get that AFR where its supposed to be along with the timing (sure its lower if tuned for 21#) and you'll pick up considerable power.
Its possible that you have a mechanical issue causing the rich AFR but I highly doubt it. I wouldn't worry about a thing until you get it tuned correctly for 17psi.
Yeah, I won't be doing anymore WOT pulls for sure...I CAN afford a rebuild , But don't want to spend that money for damn sure till the end of the year where I can throw a 5.0 Stroker in it with high comoression.I personally would not be happy if my turbo car only made 600 at 17 pounds. All the extra effort for the turbo for pd blower numbers that just not me. But as said above I wouldn't go WOT anymore until you get your tune on point.
For anyone that was interested in more info , I had my Car dyno tuned yesterday .
But took alot of peopels advice and DID in fact perform a compression test with the highest being 175, and lowest being 160.
Car made...
507rwhp/533rwpt on 10psi
619rwhp/622rwpt on 15psi
693rwhp/641rwpt on 19psi
All pulls were @ 17 Degress of timing.
Those are my current settings.
took out fuel and added timing pretty easy if you know what your doing. Those new #'s look nice OP!That looks better. Do you know what all changed?

Yes.That's on 93 pump gas and 8.5:1 compression?
