I've had the JB+ on my car for a few months now, and I love my mini. I had to take off the JB+ because my car is due for service, and I'm shocked that I can't tell the difference really. I was expecting there to be a major noticeable difference, but there just wasn't. Since I'm not taking my CM onto the track, and have plans to get a tune next spring, I'm contemplating selling it. Has anyone else in a CM not noticed a big difference with their JB+?

BTW, Yes I checked that the dial is turned to 50% like it should be, and no I haven't had any CEL's.

 

Did you let the car sleep for 15 mins? And doors locked with the hood open slightly? Also, disconnect your battery too. That might help whatever is going on. Email Terry too, he might be able to help you out. We can't really help since we didn't build the product.

 

Yes I followed the install instructions, I just am not feeling a difference from stock

When I had it on my wife's CMS for a weekend road trip, I took it off per instructions, and she felt the power for a couple days afterwards.

Got to drive it out or disconnect battery.

 

That makes sense. I just remember reading other articles on nam where people talked about how noticeable the difference was when they took off the JB+, moreso then when they put it on. I'll give it a couple days and see if I notice a difference. Thanks for the input.

 

i dont feel any difference with JB+ too ........


whats the boost PSI when JB+ is installed ??
waht is the Stock PSI is ?

 

Depends on the climate change.

 

i have it since Feb 2014,, im in NYC... how much PSI does the turbo boost spike.

 

MCS spikes at 21-22psi. I get 17-18psi. Without the JB+ I get 12-13 consistently. I live in Michigan.

 

What car do you have it on? Did you install per BMS instructions? Have you read through the BMS Tunes threads? There are a lot of variables. Did you have your car for awhile before putting the JB+ on your car? Boost can range from about -2 psi up to +19 psi w/ the JB+. How are you monitoring your motor? Not many people are disappointed w/ the JB+. Maybe also there is something amiss w/ your car.

 

All true. I get the same readings.

 

i have it on 12 CMS ALL4, i left the hood open, locked the door for 15mins then install, i have about 20000 miles when i put the JB+ on, and i am using UltraGauge to read the PSI... its read the same PSI as stock.... and i really dont feel any differ...


i spike at 14 PSI on JB+ same as Stock.

 

Email Terry @ BMS.....he will help you. Might be a faulty JB+. Hope you get it fixed.

 

i reinstall it today, and i can feel the increasepower right away... it feels good

 

Nice!
