I bought this turbo boost gauge hoping it would give me accurate readings, but it was a huge disappointment. The LED light was too dim to see clearly, making it nearly impossible to read in direct sunlight or at night. The gauge itself was also inaccurate, showing fluctuating numbers that didn’t reflect my car’s actual boost levels. I tried recalibrating it multiple times, but it still didn’t work as expected. The quality of the materials felt cheap, and I didn’t trust the accuracy of the readings. The installation was a bit tricky, and it didn’t come with all the necessary components to hook it up properly. Instead of giving me peace of mind about my engine’s performance, this gauge left me uncertain about my car’s true boost levels. I ended up removing it because it wasn’t providing useful data. This product didn’t perform as advertised, and I would not recommend it to anyone looking for a reliable turbo boost gauge.

Best price, works, and is simple. The key here is color coding, all you need is; white to power (switched power not constant) , black to ground, green to distributer or your cto wire, yellow to light switch if you want to illuminate it… thats it. I don't know what red is for as it doesn't power it, the white does. Yes the housing on mine was strange but can be modified easy. See the other reviews for instructions on setting # of cylinders.

Very, very cheap - meaning it's extremely inexpensive and probably a good deal if you just need to measure rpm when doing engine diagnostics. However, it's also very cheap in the "janky" way. Flimsiest plastic you've ever seen, and mine was broken right out of the box. It's like something you'd get at the Dollar Tree. You will not want this installed in your car.

It was an easy install, and if you read other reviews, some people complained about the O-ring that actually holds the tack inside the housing. It was too big and too tight. I just took it off and replaced it with a rubber band and it fits nice and snug but not so tight that it’s gonna break anything. I did not wire in the back light, I did test it, and it is extremely bright, too bright that you don’t want it Shining in your face at night, without having some sort of dimming going on. That’s why I only gave it four stars. It runs through the rpm range smoothly.

I Purchased this to tune my engine and dont plan to install it in the vehicle. The gauge works, looks like a $30 gauge, the backlighting is way too bright (this could be a flashlight), and the gauge does not fit snugly in the very cheaply made housing. Due to the poor fit into the cheap housing, you cannot mount this gauge without some engineering. And the housing looks like it will break. I would not install this in a vehicle unless I didn't care at all about looks and didn't hook up the backlighting. The gauge itself is accurate, it was easy to set it to 8 cylinder mode and it did the job of helping tune the engine. I would buy it again for that purpose but if you mounting it in the vehicle, pick something else.

For the price, and judging by many of the reviews, I didn't have high expectations for this tach. To my pleasant surprise, it actually works quite well! I compared the tach's reading with an OBD scanner and found the RPMs to be nearly spot on. Quite amazed by this little gauge given its price point.The instructions were garbage though. Just a single page of paper with a poorly laid out schematic for all of the gauges this company manufactures. It had no instructions on how to properly calibrate the tach - which I suspect is the issue with most of the reviews on here. You have a set button in the back and you have to set the proper number of cylinders for the tach to get a proper reading. With no instructions to go off of, it took me some time to figure this out.Overall, very happy with the product!

Gauge reads anywhere from 10-20lbs off, and is not even consistent. Measured against several known good air compressor gauges, as well as a Mityvac. It was too cheap to bother returning, so I cracked it open to see what I could find. Everything inside appeared to be in order, no obvious obstructions. The gauge face is non-adjustable, meaning you can't rotate it to resolve inaccuracies (moot, since this one reads different every time you apply pressure/vacuum).Not necessarily a con per se, but the backlighting is a BRIGHT blue LED.
