1995procharged

ok i got this mustang about a week ago and here is what has been done to it before i got it. The body is a 1995 v6, the engine is a 98 4.6l gt and it has a procharger on it. As far as engine mods it has the pro charger a 75mm throttle body a 90mm SCT senors, Ford racing heads,12lbs pulley giving it 12lbs of boost, its runing on 32lbs injectors and it all so has the 2:55 fuel pump. It has the stock v6 suspension set up on it. the rear end is a 8:8 gt rear end. the guy i got it from had it dynoed and it put 425 hp to the wheels
Here are the ?'s i have. The mustang wants to keep dying on me when i come to a complete stop like at a red light. I dont know if i need bigger feul injectors or if it just needs to be tuned. I was thinking about changing to a 10lbs pulley and seeing if that would help. Then what kind of suspension should i put under it? And i dont know what gears to put in it i was thinking 4.10 gears if anyone can help me a really appreciate it thanks

You're in the wrong forum... this is for 60s to 70s year model mustangs.

and To your question.... it probably needs to be tuned... OOOOR a sensor is out.... OOOORRRR... Injectors.... Probably timing is off... Sounds like it needs to be tuned...
