Morning guys

I have a problem that is annoying me, In december i had my car remapped at elite remaps. Drove the car home and was well impressed, pulled like a train but the turbo seemed excessively noisy to me, anyway got home and drove kids round to friends and drove home then had to pop out to shops. Just rounded the corner and lost boost turbo was still spooling loudly but no boost at all, looked in rear view mirror to cloud of blue smoke, great turbo was gone, think it was on its way out anyway as it was always noisy. Had a new turbo fitted at the weekend and also a 710n diverter valve. Whe the car is ran from cold, runs fantastic holds boost all the way up to redline no bother, but as soon as its slightly warm there is an annoying hesitation or split second loss of boost, thi is only under hard acceleration, under normal driving its fine, could it possibly be the wastegate momentarily partially opening or am i looking at the wrong ideas, any help welcome

Cheers

Quick update could the n75 cause these sort of symptoms?

Is the actuator arm on the turbo moving when you rev it and is it moving when you turn it off. This is s variable Vane turbo so no waste gate. Regards Peter
