Hey guys just picked up this beauty and looking for a little advice as to what i need to do next or improve? Abiut how much hp its putting out? Air fuel ratio seems to jump around goin from 14-16 cruising and hitting around 10 at wot..... i was thinking 42 lb injectors?

Here's a couple pics

Yes stock npi motor... and boost im not to.sure i believe the belt is slipping.... pulls strong still but only shows a max of 3-4 psi.... belt looks a little worn so i have another on the way.... any opinion on the injectors?

Just asking simple questions for a little more knowlege as to what i have and ppls opinion.... i am unsure of the where the air fuel ratio needs to be...i have owned many stangs but none that where charged so any "POSITIVE" insight would be appreciated.... but yes the car will see a tuner soon.... thanks

Honestly im not sure ill look at them tom. What are some other mods yall believe would benefit this car? Not looking to spend to much money but would like to see 300 rwhp out of it..... i know the pi intake swap wouldlike benefit it and a smaller pulley... opinions?

Thats what i was thinking... wanna take a stab at how much hp shes putting down?
