It's a slippery slope, First an AFR gauge and next thing your installing EFI 

AEM 30-300 4.7 out of 5, 163 reviews on Summit Racing. Pretty damn good to meI'm reading lots of bad reviews about AEM, with many people saying what they bought worked incorrectly or quit working within a month or two of purchase.
Hit me with some other brand recommendations please.
9 one-star reviews on the first 2 pages on Summit - most saying they broke or the sensor didn't work. The review average may be 4.7, but I always read the first 3 most recent pages to see what bad reviews are mixed in with the good. Hoping to find an alternate that is universally liked if possible.AEM 30-300 4.7 out of 5, 163 reviews on Summit Racing. Pretty damn good to me

thanks for this. I have watched Thunderhead289 videos before, but wasn't aware of this. I checked out the Carb Cheater online this morning and it looks pretty cool. I'm going to email him and see if it auto-tunes well if driving through changing elevations. My car was already dyno tuned for WOT, but I'd like to tweak things some more for the entire rpm range.You could install the Carb Cheater and just let the computer adjust the AFR automatically for around $500. It works on any carburetor.
I have not used one but it sounds like a winner for a novice and it's quite a bit cheaper than a fuel injection conversion.
Thunderhead289 sells them.
wow, that Innovate LM-2 is EXPENSIVE.See post #2
But the AEM isn't.wow, that Innovate LM-2 is EXPENSIVE.
Ordered AEM 30-0300 today.This info is great timing for me as I’ve been reading on purchasing an Afr and a vacuum gauge for my new engine build.
I appreciate the input.
