Mosfet number 3 keeps blowing

Already replaced all 6 mosfets but number 3 always blows when i do a hard pull, anyone know what it could be?

Change your injectors, the resistance is likely bad on #3 causing it to repeatedly blow.

Injectors could fail electrically?? This is new information to me. I thought they all just got gunked up.

What index are you running OP?

I had injectors bring down my BSD link. It was awesome when the car hit 18v and everything went haywire. Never effected the transistors though but injectors can do some weird voodoo.
