So you need to specify what you have (cams), and also your vacuum routing and a video and describe how you are actually testing this. (2500rpm cruise) then (Full throttle pull to 7000rpm).etc if you are using 50% throttle then you're just spooling too slow and your test results are normal.

Ok I will make it a video today hopefully. But its a stock s14 Sr with s15 turbo (its the turbo that came off the automatic s15's not the ball bearing one) 550 injectors, stock cams, fmic, straight exhaust and a turbo header. It makes full boost from 4k to 5k but after that the boost drops to 10 psi and it stops pulling and it starts back firing and running rich so I never tried redlining it cause I'm sure ill blow it up if I tried. Do you think I might of set the boost controller wrong? It's a tru boost AEM
