Front end gets real flighty under WOT

[JOATMON]

I wasn't really sure were to ask the question but I guess it doesn't matter. I'm aiming this question at the remaining members here that have or had high horsepower 4th gen F-bodies.
Some may remember I did a complete top end overhaul, corrected valvetrain, springs, etc. on my Camaro. Along with a fresh opti, higher lb/hr injectors and higher capacity fuel pump. I brought my PCM to a local tuner(LT1 veteran)and had him go through the tune, injector constants, etc.
The car was fast when it was running shitty, now it's seriously fast. Backing up just a bit, when I did the true dual Hooker Blackheart exhaust, I also fixed a pinion seal leak and replaced a bent BMR torque arm with a frozen up heim joint that couldn't be adjusted.
Continued to next post, timer running out.

I reset the pinion angle and front torque arm mount. I also did the wheel and tire package that included a pair of 305 Mickeys out back.
After test driving the power increase was very noticable, with no top end breakup from lack of fuel capacity.
The car was driving real wonky for lack of a better description. I discovered they cause was that three out of the four brake calipers were sticking.
I replaced the calipers and rotors and use braided SS brake hoses. Problem corrected, car drives straight, doesn't pull to either side and brakes better.
Continued timer fixin to run out

After driving it and doing acceleration pulls, holeshot rips, etc. I've found that if I really rev it and side step the clutch I still blow the tires away all the way through first and second. Zero traction, BUT, if I rev it and feed the clutch in easy the Mickeys hook and it gets reasonable traction through the gears.

Now that I've presented all the facts, I'm aiming this question at all the high horse power F-body guys here.
When I'm running through the gears at WOT now, the car really lifts the front end any time my foot is all in it.
It drives really squirrelly any time I'm at WOT. When I get out of the throttle and the body sets back down, it drives perfect.

So, what do ya'll think is happening here? I'm I at a horsepower level thats constantly trying to lift the front tires under WOT? I "THINK" its making maybe 500-550 at the crank.
Does your high HP 4th gen act like this?
What do ya'll think is going on here?

305/45r17 @ ~26-28psi on the street, hasn't been to the dragstrip yet.
I may need to check again, but the panhard bushings were good when I did the torque arm. I did tighten them up because I found they were a bit loose.
I remember because I put a Founders panhard relocation kit with the offset body brace to gain additional exhaust clearance.
Panhard bar was level and tight.

on osies procharged car the 275/40/17 always felt soft even with 26-28psi. it would spin like hell but always felt squishy

Is the steering stable or darty on the Bird when you make a wide open pass?

mine is stable but im on skinnies and no front sway. osies gets a little darty with 275/40/17 fronts but his car is kind of stock alignment with a hair more negative camber and the max caster we could get, by eye/angle gauge . they both need to get an alignment lol
