Well to start off I just installed a supercharger on my mustang .the upgrades are:
Vortech v1 s trim
Rebuilt 302
Holley aluminum heads
Holley sytemax 1 inch spacer
75 mm tb
custom ground cam
42 lb injectors and matching MAF
340 stealth aeromotive fuel pump with upgraded fuel rails
Now my problem is when I start the car on a cold Starr it turns on a idled just fine but after it warms up and I give it gas the car dies and dosent wanna start . It will take a couple try and then it will start and then do the same thing and die .
My spark plug wires are brand new , spark plugs brand new too 3923 I think gapped at 32 . Fuel pressure stays at 41 . I'm kind of stuck for now I know I will need a tune but I dont wanna take a car that turns off to a tune shop so any help will be much appreciated thanks.*I'm thinking of changing sensor on the distributor , my coil? I'm thinking it can be a fuel related issue with the fpr? Or a bad or dirty maf? The car will idle fine no surging or anything just when I go & give it gas it will rev up and die out.(

My guess its the MAF once it goes into closed loop.
Gonna need a basic start up tune so you can drive it to the tuner unless you tow it.
Its just getting way too much fuel at tip in and flooding out.
Try unplugging the maf
Also try clocking the maf at 90* intervals
