Anybody here use the GRIMMSPEED boost controller? I've seen some reviews on their website but I want to know if it's better than turboxs boost controller.

 

It uses the MAC solenoid like anything else that people on this forum find popular.

A turbo XS controller is a manual controller. They act differently

 

Shodan, Grimspeed makes a MBC as well, and I might be crazy (I blame the booze if I am) but I don't see where OP specified.

 

This is the boost controller I'm talking about. What is your input on this manual boost controller?

 

True.. I was aware of the fact they make a manual one, and as you stated, OP didn't specify.

I like it. It's a nice bleed off style unit with clear markings, and comes with all the legal disclaimers a good company should have.

This is a second place choice to the Hallman..

If you haven't tuned the car already, (no basemap!) Then this should only be installed on running day, and not a moment before.....

 

I agree with all of this 100% myself

 

I'm running AEM v1 and I'm just swapping out the block with a sleeved block. I'm using turboxs MBC but I wanted to change it to something better and I found this one that has markings on it so I know how much more/less boost I'm giving it. Of course I'm going to get it retuned but can I put it on during my start up with the new block I'm putting in?

 

Retuning isn't necessary as boost pressure = boost pressure. If you ran 10psi on a turboXS, going to a Grimmspeed changes nothing. The only way a tune is necessary is if there was a terrible boost leak in the system the 1st time around.

Hook it up and go. Stay within your tuned boost pressure ranges, and you're fine.

 

Yea I get you. The only thing I don't like about the turboxs is that you can't really gauge your boost like the grimmspeed MBC. Those markings on the controller will help a bit don't you think. The grimmspeed MBC clicks and it says that each click is .25psi. The markings help a lot too don't you think?

 

I've had MANY manual boost controllers. the problem with the turboXS was that the control **** rotated on its own after a setting over a period of time.

Hallman, TurboXS, TurboSmart, Dejon Tool, etc. NONE have readable markings, and all work.

If you want to be sure you're at the right pressure, Use your boost gauge before and after your adjustments and don't just rely on a "click" with a number marking.

It's more convenient to have the markings, but not by that much because you can't compare it to what the boost gauge reads.

 

Got it! Thanks a lot!
