Wanting to know if anyone knows if this gauge is accurate or not, I don't want a cool looking light show like the standard A/F ratio gauge are typically used for, I want actual good accurate information, and for the price of this AEM gauge im wondering if you get what you paid for.

Thanks

 

yes, mine was but if you go under 11:1 AFR it will not read

 

Well damn, that just sucks.

 

I guess your running pretty damn rich if it doesn't read then!

So for a tunning and good driver in car information you would suggest this part?

Thanks

 

on a turbo car for tunning safe, it nice to have really rich and bring it up... the problem was it was 9:1 and the guage didn't peg out........ it would bounce from 11:1 - 11.5:1

for a NA car or more experanced tuner it will work perfect. i didn't want to pop my motor tho
