Then the comparison is pretty pointless and I would not hold it against the new numbers as who knows how much of a hearbreaker the new one is over the last one.
Idk if I'd expect 470rwhp out of your setup, especially with smaller diameter primaries and a 78mm stock MAF. Bigger cam, FAST manifold, free flowing intake and bigger headers maybe.
Before you drive yourself nuts, check to make sure the tune is spot on and take it to a track to see what it traps. Till then, you're just pissing in the wind with guesses and random unachievable power expectations.

My 470hp guess was with it optimized with 1 7/8s, Fast 102 ported and a SD tune. I thought I clarified that but if I didn't I did now lol.
I agree about seeing what it traps. In the end the is a great indicator if it's just a heartbreaker dyno or the setup needs work. With the heads being ported it would be advantageous to get a better flowing intake as well.
As your car is now I would expect in the 420-430 range at least.
If it doesn't trap AJ if look into SD or a larger Maf and larger LTs paired with a cutout to bypass the CME.

Took my car out for a spin earlier today and every time I try to leave first gear aggressively my car starts to bog and sputter. When I cruise on the freeway in 6th gear it feels like I have no power and all and if I step on the gas the car starts to surge and it sounds like it's back firing. I spoke with the tuner and he said it sounds like I need to get new O2 sensors and enable the MAF and do a MAF tune instead of a SD. What do you guys think?

Sounds like you need a new tuner. Switching to a MAF isn't going to magically make your car run better, and unless he saw specifically that the O2s are not working sounds like he's trying to throw some more of your money at the car in the hopes it hides or masks his shitty tune.
definitely seems tune related.

I've learned the hard way that just because a certain tuner and/or shop has a great reputation, that doesn't mean you'll get a great tune. Mine is world's better now by a guy who basically tunes out of his garage but is very very good. Had the car for 4 days and fine tuned every little aspect. Sometimes that's not something a high end shop may not do because it's not cost effective for places that have a high volume business. My original tune by Vector Motorsports was like $400 and the tune was garbage. Basically took my car for a day and made sure it idled well and was good a WOT then gave it back...all the in between was crap. Something to consider....

^ all of the above..
So it's actually driving crappy too. That sucks. Hopefully you can find a good tuner, to take the time, to make it right.
The tune I received, from a reputable shop, is pretty good but I still have stalling problems.

It sounds like its running lean and your VE table is jacked. What was the AFR when you had it on the dyno? If he cant tune SD, he wont get the MAF tune either. I would find a new tuner.

Was it a load bearing dyno? If not did he drive it around and tune it as well? Some shops say they can tune but cant! There is a place by me that is a big speed shop and the guy they have tuning cars is terrible at it and only knows how to tune wot which is no good for driving around.

I would recommend either making an appointment for him to check it out or find another tuner if you're fairly certain it's not a mechanical or electrical issue.
A bunch of questions based on an internet thread questioning his work isn't going to make your car run better, but it will certainly build resentment and eventually he will probably just start avoiding talking to you.
I don't know enough about a SD tune in general much less one that doesn't use o2 sensors to offer much advice.
