I recently installed a 3" test pipe and flashed a stage2 cpe nano fmic tune with my AP. Since then I have noticed that when I go WOT at about 3500 rpm I get an annoying high pitched whine that appears to be coming from the turbo. I'm thinking this is not normal. I don't notice the sound any other time that I am in boost, just WOT at higher rpms. I never noticed it before the testpipe install and stage 2 flash.

Is it safe to run a stage 2 tune with a test pipe?

I really need to try and do some logs, but from watching the dashhawk, my wgdc seems very low, only reading around 50 max.

Yup, that's normal... Heard it after putting on my 3" TP as well.

Hmm. I never got a high pitched whine after the testpipe install. I think the turbo sounded the same. Even after a down pipe I didn't tell a difference in turbo sound. The TIH was the only thing that made my turbo any louder.
