my boost guage is reading that i creep up to 14 psi MAX and usually boost 10-11 at wot. my rtek is reading that I hit 15.8 psi at 3k at wot, which is obviously not true since my turbo is stock. im assuming the problem is the map sensor since thats where the rtek gets its readings from.

the sensor reads vacuum and light boost properly it seems, but fails at higher pressures.

I regrounded the sensor and it didnt fix it. just wanna make sure im gonna buy the right part. thanks
