I'm new to the forums but have been reading extensively for the past month. I did search and the forum is just filled with all the answers i ever wanted.

One thing i couldn't find was, if i have an EBC (set at 22psi for example), will it spike or ever change with weather changes like MBC?

i'm debating weather to get a greddy spec II profec EBC or the hallman in-car MBC. I don't mind the difference in price as long as the EBC holds the same constant boost level in all seasons.

Cheers

 

Forgot to add, i will have an ECU mail-in flash by the time i get my EBC

 

I just had my greddy installed I love it man.

 

Yes the weather will change the boost. It will make it spike. With the weather here i have to adjust it in the morning, in the afternoon and then at night cause of the weather changes. Get a electronic boost controller. They control boost better especally with weather changes. I never had to adjust boost on my turbo 240 with Profec B II once i got it dialed in. Im planning on getting a Blitz SBC iD to replace my MBC.

 

ebc..i live in miami ...weather is hot...all the time... can get to the 40's ...never a huge fluctuation in boost

didn't want to open a new thread, does anyone have the AEM Tru-Boost controller?
i searched and found only 8 or so threads only.

 

i wouldnt recommend the greddy unless you can fine tune it. i thought i fine tuned mine, then on the dyno it was holding 19psi while spiking to 23 psi. i havent had an MBC yet, but i'm getting one for occasions such as this so i know what boost i can hold and that it wont spike or not hold boost until redline.

I thought the AEM was only if you had EMS? I know we were going to use one at the dyno and let the EMS control the boost through the AEM tru-boost solenoid. Then again, i could be wrong.

AEM Tru-Boost seems like a solid easy to use boost controller and gauge. According to their website, it is a standalone controller.

anyone have any experience with it the tru-boost?

 

You'll have less boost spike with a properly tuned EBC than a MBC.

 

I have found that my EBC spikes to 24.7psi Max prior to that was 24.0psi. during the last 2 cooler days here in the high 50's... The car feels great. I just leave it alone. It holds 23 for a little while but as the RPM climbs it settles to 21-22...

 

That's great to hear.

I'm definately going with an EBC then. Just wondering if anyone has tried the AEM Tru-Boost controller ..

 

I would have to tweak my EBC after the weather changed like 30 degrees. No biggy though... just a slight twist of the knob on my HKS EVC On my Nissan, the stock wastegate was set at 7.5psi and I kept it there 99% of the time. But once in a while, if I needed some more power instantly, just a quick hit of the button on the EBC and I had 11-12psi!
