My RST when im reving up above 3000rpm it hits like a fuel cut and sometimes it revs up spot on. My acuator wasnt holding alot of boost could that be the promblem?

 

possibly - whats your boost set at? Has it got chipped ecu? Need more info m8.

 

Its a t34 turbo its EFI set up and it running cossy managment. Its set at 10psi at the min the guy that was setting it up said it was weak thats why he only set it till 10psi cause he said if he screwed it the whole way in he was only gonna get 15 at the max. Wat else could be causing it man? Its a really bad cut out.

 

Could be an electrical problem? Spark blowing out? Check to see your gaps are correct - if the guy was setting it up wouldnt he be able to tell you?

 

Yeah mite take it to him and see wat he says. There is a set of spark plugs not long in it NGK iridium. Wats the best plugs to use? I had just NGK ones in it and they didnt last very long till it started missin a bit pretty much the same thing this time only this is a bad miss. Y would it be goin thro plugs so much?
