28lb injectors will be good for 450HP on a dynoject, or around 400hp on a mustang dyno. Should not come close to maxing them out yet.
The stall is already a large concern, it is flashing very late.
Next is the AFR, sounds like it's running LEAN hence the high duty cycle of the injectors. High duty cycle is an indicator of inadequate fuel. Does NOT mean the injectors are not capable of providing the fuel given the circumstances.
Fuel filter is an option, but I'm more inclined to lean towards bad tune IF you can 100% guarantee that all the rest of the parts were installed properly like say the cam.

Are you still running the car on 8 month old gas? If so that's definitely a problem. You need to put fresh gas in there before you run it WOT again. Then you can run the car with a fuel pressure gauge attached to verify a good fuel supply.

Brett Foote well the stall has been like that for 10,000 miles since i had the car its driven the exact same with no problems and yes im running the old gas i had a quarter tank of old and added like 6 gallons of fresh super
I know man. I was just messing with ya. 
Even if it was a 5k stall it should at least do over 300 but who knows mabey its a 5500 lol than i could see something like that being the cause of the problem but its only an opinion not the facts and thats whats we need i still say you take it back that reputable speed shop or atlease have another opnion by another... Back to the point! Take it to the track and see what it does cuz if its got a 5500 stall or even a 5k you should cut a pretty nice short time lol and run pretty good...
i talked to my tune guy and hes seems really chill im going to bring it back after i add the bigger injectors and hes going to finish tuning it and do a quarter mile run on his dyno which he says is very accurate for free to see where i stand
If it's a 5000 stall and you cut the pull off at 5300, yes that would severly effect the #s. I still doubt you need bigger injectors yet. I'd figure out the stall issue then if you need injectors do that.
well the car was fast before so its only going to be faster with the cam and the longtubes im just gunna throw some 36lb injectors in there go back finish my tune and deal with the stall problem later i can always take it out and have it restalled to a 3500
your injectors cant be maxed out my freind did head cam swap with stock injectors put down 396 at the wheels(after injector swap lost a couple ponys). the best thing i can tell you to do is take it to the track see what it runs ,dyno's lie tire slipeing bad dyno any thang is possible does it fell stronger know than before have you ever ran the car? either the tune is wack are the dyno is bad just worries me the tuner said you need injectors? dont sound rite.
Get 42lbers It will pay off in the long run plus why spend the same ammount of cash on something inferior? The thing is you will regret the 36lbers once you start maxing those out because theres realy no way to max out the 42lbers so your good forever oh and 28s are stock for the record...
