hesitation on boost
 

Hi guys
1998 uk turbo with exhaust and induction kit ,was running fine until today,ironically on the way to jae !
Only cruised on the A1 but when i went to pull away from roundabout and nailed it in second ther was a massive lack of power followed by a black smoke cloud and now has boost to start off but looses it quickly and a funny ticking noise which is metallic but lightly rattly
any ideas cos i am scratching head:wonder:
