cutting out!

[C3 LJG]

Have just got my ibiza cupra and have fitted dynatwist, forge 007 dump valve and cat back scorpion exhaust and when you get to 4500-5500rpm it cuts out like its hitting the rev limiter and pops through the exhaust.

Has anyone got an idea what it might be? Its booked in for diagnostics on friday day morn just woundered if anything i could try first?

:confused2
