2871r vaccume question

[zoototheyork]

before i was using t25 now im useing 2871r-.64
@ idle
vaccume with t25 was at steady 20
vaccume with 2871 is around 14

car runs like a maf prob or vaccumeleak

is that normal vaccume?

sounds more like a vacuum leak somewhere to me. Trace all your hoses and lines and look underneath them as well, they can crack underneath and you can't see it

anyone else with this turbo having differnt vaccume reading?

I dont have one personally but a friend went from factory t28 (blacktop) to a 2871r and vacuum stayed the same. So id start replacing vacuum line until you fix the leak.

Your vacuum should stay the same, you have a vacuum leak somewhere. Where are you getting the reference for your wastegate and check any plumbing you may have removed when installing the new turbo.
