I would say around 340-350 with a tune, your MAF may be making your A/F ratio a bit off.

Well like, most cars (especially M6's) do get around 340-350 with full exhaust and a lid, ported TB and some free mods. Your true duels probably add more than my magnaflow cat-back and any cat-back for that matter so I am assuming you are both higher than 320.

the td's will push the power up the power band further...you will lose some torque...but you'l more than make up for it in the top end.
if you would like to be closer to 350 rwhp with the m6, get dyno tuned. that is usually good for around another 10 rwhp

I would say you should already be at 320rwhp. I have an auto with the SLP lid, K & N filter, SLP 85mm MAF, SLP Smooth bellows, ASP underdrive pulley, Hooker cat-back, Flow-tech Exhaust Cut-out, 3500 stall converter, 3.73 gears, B & M tranny cooler, LS1 Edit dyno tuned. And I am between 315 and 320 depending on weather ofcourse on a mustang dyno.
And it is also a 99 model still with the LS1 intake and stock manifolds.
You being in a M6, with just the basic bolt ons you should be around 320 if not a hair over. I dynoed bone stock 316 at the wheels. The stall and gear combo knocked me down to 290 though
LS1 edit gained me back to 308.
I haven't had it dynoed since I installed the flowtech cutout and underdrive pulley but from other peoples gains and my improvement at the track (.25 increase with both mods together) I think I'm at 320
Once you install the LT's you should be 340 easily. And with a good tune, 350 or even 360 is attainable. Throw in a LS6 intake for good measure as they claim from these boards at least 10hp and you should exceed that goal easily.
I'm going the same route with my A4. . .and later shoot for 400 at the wheels going cam only or heads/cam combo.
Good luck and post results after your LT's as I am thinking about the flowtech headers too.
