Default Dyno estimates for the new setup?

Car's going to Speed Inc in the morning to get the dynotune finally. Just looking for some estimates before it gets tuned in. The car is a 6speed with stock 10bolt with 3.42's (Working on 8.8" rear with 4.10's, but obviously won't be done and installed by morning lol).

MODS:
6.0 LQ4 stock shortblock with fresh rebuild (ARP rodbolts, all else stock)
TSP 231/236 .644"/.613" 111LSA cam
Stock L92 heads with PRC EHT .675" lift valve springs
Stock LS3 intake/rails/injectors
SLP lid
Ported MAF ends
Nick Williams 92mm TB
Ebay 2 3/4" primary/3" collector stainless LT's
3" Xpipe (no cats and Borla ProXS mufflers)
RPMSpeed 255LPH fuel pump
Racetronix fuel pump hotwire kit
Spec Stage 3 clutch

Any guesses? I'm hoping for ~480rwhp, but that may be wishfull thinking. Numbers with a video and dyno graph should be posted sometime tomorrow night, whenever I get back and have time to get them put on here.

Well, everything felt like going wrong today when we put it on the dyno. Fuel issues, big time. I lost pressure at around 6k rpms, so they had to shut it down. Not to mention, when I first got there, they had to have a new MAF brought over from the dealership, because they wouldn't tune it with the ported MAF ends. Luckily, they got me a bigger MAF, so I'm not as worked up about having to get a new one. Figured we'd be good to go from there, but of course not. So, a long trip, and a lot of money wasted for nothing. Looks like I need to get some fuel issues worked out before finally getting her dynotuned. Definately not happy with how everything went though.

I'll say 450/420 because you have the L92 heads, w/great midrange and a top end that dies off fast from the 111 and shorter exhaust duration. You could be right on the 480. Those heads are performers for sure.

They weren't able to mess with the tune much, because of the fuel pressure issues. But, the run they started on, with a base tune hit 418rwhp@~5600 and 392rwtq@~5000-5100. Then, the fuel pressure dropped to 30psi, after that. So, they shut it down, and just did a little tweaking to make driveability a little better for now. But, it looks like I need to change this damn fuel pump already. This car is a damn money pit. I am happy they had a GM 85mm maf sent over from the dealer instead of a stupid stock MAF though.

Nope not yet. Had some other things come up and haven't been able to get it tuned yet. I think I got all the issues figured out though. Just need to get a fuel pressure gauge and check it sometime soon. Then, I'll get it tuned and have some numbers.
