## Customer Reviews

### ⭐⭐⭐⭐⭐ Quick shipping, seems great.
*by R***  on April 22, 2022*

So far so good. Nice to have a single gauge that shows ethanol %, AFR/Lambda, temp, and pressure.

### ⭐ Does not bring a 10 bar fuel pressure sensor
*by A***R on October 12, 2024*

A lot of stuff was apparently missing from my kit I didn’t notice it till now when Ive finally got the time to install it.It works but I’d say check all the contents a lot of stuff could be missing.Installation was rather difficult but not too bad.For the money I’d rather just go for a E85 gauge for less. A lot do the functions of this gauge require extra stuff either I’m missing or just gotta pay even more for it which makes this insanely expensive for what it comes with.Innovate does make good gauges and is built well just keep aware of the other issues that can come up. Foment is really lose in most gauge pods I had to use double sided tape to keep it in place.

### ⭐⭐⭐⭐⭐ Works awesome and very easy to
*by K***S on February 18, 2018*
