thanx for ur help guys ive sorted the boost im running 11psi at the mo

the starting problem would it be the starter motor cos my one is some big thing and someone said it might be the heat from the turbo doing it

as for my chip its a turbos systems one my mate said it runs 18psi

and the engine was rebuilt and was run in before i got it cos the car was a rusty one failed its mot after the engine had been run in

any more help would be good thanx guys
