Have you got all plugs plugged in correctly?
Timed up correctly?
I once had similar problem, and IIRC I had my CPS and dizzy plug or maybe MAP sensor or similar plugged in back to front - can't remember exactly what I had plugged where, but car drove mint off boost, then popped and banged on boost.
Swap plugs so they are right and it worked sweet

my dizzy plug wires were damaged and i re solderded them tohether could they be the wrong way round
Could be, but you would need someone clever with electric stuff like Stu, Dingy or Ryan to help you diagnose that.
I guess there is a way to test it, but I wouldn't know as I'm not as clever as the above names!
