Works perfect

By Josh S on March 19, 2020

I have a 2014 Silverado Z-71 and I just installed it and wow! I can definitely feel the difference love this, it’s definitely got more power and the transmission shifts smoother now I highly recommend this.

Transmission bangs

By David O on August 5, 2020

This didn't seem to work on my 2016 GMC Sierra SLT, transmission slammed at low speeds and it blocked OnStar diagnostics. I returned it to be updated and it came back, nothing seems any different, trans still slams and OnStar is blocked. Was told oh well take it out when OnStar runs, like I know when that is. Nice customer service, wasted money. I was contacted by someone higher up regarding my review and he offered me the opportunity to return the device and get a full refund. So I chose that and I received the check today, they're customer service raises the rating.

This turned my 2017 Silverado into what felt like a sluggish four cylinder car half the time to full power and even noticed smoother shifting of the trans great product

RA003B excellent product

By Larry C on February 4, 2021

recently purchased a 2011 GMC yukonXL with a 5.3L engine was disapointed with oil consumation. my brother-in-law suggestedthe Range AFM plug-in RA003B. I was using about a quart every 1500 to 2000 miles. I installed the RA003B and changed the oil the next day, after 1000 miles would normally have been at least a pint low still on the full mark Plus the exhaust sounds better and transmission is shifting smother in town. Purchased from Summit Racing

Good product, minor flaws

By Wes M on February 21, 2021 | Verified Owner

Two issues holding it back from 5*s. 1) I have no way to tell if it's working. I'm trying to see if I can "feel" the difference, but the AFM is pretty smooth on the 4.3L V6. 2) It was not clear to me that it has to be unplugged if you're going to go more than a couple of days without driving the vehicle. Apparently it draws electricity and might drain the battery. Great. Another thing to worry about / have to remember. Wonder if this is just the lighting or if the device is drawing? Cause I could do without the lights...

Smooth as Tennessee whiskey

By Terry R on May 28, 2021

I didn't even realize just how rough my 2011 silverado was running, that is until I plugged one of these bad boys in! It instantly ran smooth from the first start. I'm really eager to see if it takes care of the burnt up spark plug issue. I'm hopeful it help control the oil consumption issue as well. One tank in and the milage is about normal usually 18mpg to work and 21mpg on the interstate.
