now i know its susposed to be 250rpm or something like that but my starter goes faster
I'm going to bring it to mazda dealership for a real one as buyer is paying for it. but its hr and half away(one in town is not good and don't trust them at all)

 

"can anyone tell me if results are normal"



Good on you for trying though, the dealer one will be useful.

 

Even if you had a compression device that held/identified the peak reading would be a tiny bit better.

You need a rotary specific tester and the rpm that xref the table
