Default heavy missfire

Right

Changed the plugs...
I had BPR7ES in them. put new BPR7ES in.

gapped at .025

I noticed one lead was slightly loose when connecting. i clamped it together and snug fit.

as soon as i build boost it just jolts the car pops and i let go of the accelerator.

Lesson to be learnt here.

check your vacuum leads

one was off. explains everything. explains the lean out on missfire.
NO FUEL!!
FPR, dampener and BPV wasn't connected!!!

My first response: you have either a pressure or vacuum leak....check connections.
