My RPM buzzer keeps changing its RPM range. Wednesday night it would go off at 7500 and now it's going off at 8000. Also, the car runs better when it makes it all the way to 8000. When the buzzer goes off at 7500 it seems to struggle to get there, but when it goes to 8000 it gets there no problem. Any suggestions?

There is no way the buzzer can affect the cars performance. No way, no how. The only way I can think that both the buzzer and the engine's performance could be affected at the same time is if you hade a serious voltage problem, but even that's a stretch.

i thinking maybe the buzzer is meant to sound at a area withing the 7500rpm and the 8000rpm range that is why you feel it buzzes a different times. its like when you floor it and what for it to get up there the rpm's don't just stop they keep going. you would answer your question if you would hold the accelerator down till you reach that area and pull back the accelerator to maintain the rpm's constant. and do that a couple of times to see if the buzzer goes off at the same time. but the stuggle is most likely because you are redlining it. the engine will hold but you'll end up busting it if you keep doing that.

Well tonight i KNOW it didn't buzz until 8K and last week it would buzz at 7.5K. Not sure what the problem is but it seems okay right now. I was thinking maybe an ECU problem? Hopefully not...
