View Full Version : AEM Tru-Boost - Too good to be true?

Alright, so I'm ordering AEM Tru-Boost Gauge + Controller and the AEM Uego wideband 02 to serve as boost controller, boost gauge and wideband A/F and gauge in one pillar (Dual a-pillar pol).

I have one question though, from the amount I've read on websites offering this, I did a search for actual application reviews (DSMforums.com / srt4.net and honda-tech.com) since those are the most expected sources for people that have used the AEM Tru-Boost.

Based on the reviews written by actual people who have tried this (not diatribe from retailers on websites about it's features), I've gathered the following:

1 - It's listed as an electronic boost controller and a lot of people have SAID (Note, I say SAID, I'm taking this as spoken experience not fact), but that it "Honestly, acts more like a manual boost controller with a digital interface performing the same functions as an electronic but in all honesty for say $40 or $50 more just go with a full electronic boost controller like the Profec B"

What sticks out most to me is the ". . acts more like a manual boost controller with a digital interface" part > ?

It's listed and sold for roughly $200 - $275.00 which isn't bad, but I've heard it closes the wastegate when it isn't supposed to (Which could be part of the "built in" elimination of wastegate creep function faulting), definetly a concern. ^ This coming from a single turbo'd supra on the dyno - 17psi run GT35R, wastegate shut on and off and another problem being boost creep and spike (Set at 17psi, sometimes only building 12 and other times 23psi).

They said the problem was definetly the gauge, they sent it back, got a refund and ran a Blitz controller, re-dyno'd and had no issues.

It's just worth mentioning since this item is still relatively new and definetly more affordable so I'd like to see some / any discussion or insight from anyone else who's used this personaly (not a friend's car, maybe for application uses like "it was easy to install and they had no problems" but first hand experience would be better).

Also, there's no external solenoid or any other device commonly found in most if not all electronic boost controller as there is w/ the Tru-Boost, found that kind of weird - getting the controller / gauge in the mail, tearing open the box and finding . . . . a gauge with two small black display buttons?

Thoughts? I'm leaning a little towards the E-Boost or AVC-R at this point, but I'll try it out first I guess. I just thought the idea of two matching (AEM Tru-Boost and AEM Uego) gauges and simplifying the need for two gauges then a boost controller and then a wideband and then a turbo timer etc . . . with just two gauges and a turbo timer, be done w/ the controls and move on to something else / more important, so I'd like to be proven wrong just want to make sure about this purchase and for anyone elses sake for that matter.

AVC-R is a piece of junk.

I havn't tryed the tru-boost personally but, have heard good things about it.

Why do you say the AVC-R is junk? In all seriousness, just curious.

There are so many settings on that thing its just stupied. Manual boost controllers are the best. But I and most people prefer something digital that you can controll from the drivers seat.

So Tru-boost, 2 buttons. Simple. No BS. One for more boost one for less.

itd be nice to start a thread with the boost controllers you guys are using and your thoughts on install,ease of use and stuff like features....

In other words, you lack the technical understanding required to set up an AVCR? That's fine but don't say that the AVCR is junk just because you can't figure it out, all you have to do is read and follow the manual (that stack of papers that you probably discard upon opening the package).

I have always had great experiences with the AVCR as well as the older Greddy Profec models.

No, I like setting the boost and bieng done with it. Not having to go though all the dumb variables. It's pointless. Pretty much all of the fastest running turbo cars out there are using, guess what? Manual Boost Controllers.

I second this. I only say this for the knowledge to be gained and money that could be saved w/ future DIY projects of new members to the forum, perhaps adding this to the FAQ.

Most if not all electronic boost controllers have an external solenoid. Blitz does, Profec does, HKS does, etc.

The Tru-Boost is a pretty simple to use from the installs we have done and with no ill effects. You tell it the wastegate spring pressure you are using. From there you add duty cycle to the solenoid to reach the desired boost level you want to attain. You do this as well for both the A and B setting which are for low and high boost usually.
