I have had numerous help from ********** thanks, but I am still having boost spike. Does any one have any ideas how to eliminate this. Yes everything is installed correctly. I used all the settings from street unit, but my boost will spike at 12 to 13 psi and level off at 9.5 psi. This is just frustrating to keep having problems. If things don't change soon the car is gone and i don't care how bad I take a lost on it. Please help with this, my number is 919-464-6873 hit me up. Is it possible the wastegate is malfunctioning.
 
lol that b.c is notorious...anyone who would recommend it hasnt had it for long or doesnt have it....
sorry i cant help bro but the profec b would of been a hell of alot better
 
I have the same issue but I expect it. My car is otherwise stock. The stock exhaust is choking me up and also my whole intake setup is stock.
 
I have hard pipes, down pipe, bov. Enough modes to support more boost. So discreet are these controllers bad for spiking. If so you recomend the greddy profec b. This sucks ass
time to get a 350z now fuc this car. Gbourdon haow bad is yous spiking.
 
I was also considering a greddy profec I didnt realize that they had soo many problems.
What is a good BC to get manual or electronic with no spiking or minimal spiking?
 
this one is great

That is the apexi right, whats the price on something like that about $700-$800?
Isn't there a way to get reliable boost control without spending so much?

dude i cant help you on that b.c....everyone i know here locally and some on the boards that have this is b.c had trouble and got rid of it...lol i remember ********** and celdridge supporting this b.c...but at higher psi its harder to control..
goodluck on that...if you get it to work, you the man.(yippy)

id recommend the profec b as a b.c., easy to tune and no spikes(unless somethings wrong with your car(RTM) )
 
DIscreet isn't that what he has is the profec b. Or is the b-2 a newer model or something.

PLease explain.
 
I have the profec 2 and it gives me nothing, but problems too much spiking when trying to run higher boost.
 
SELL YOUR CAR BECAUSE OF A BAD PART! WEEE!!

Best idea ever. Boost spike is a problem on ANY turbo car with a boost controller and small internal gate. Especially on a small fast spooling turbo like the t25. The profec b2 Shouldnt spike, but if it stays that way sell it and buy a profec B, or better yet, stop bitching about it and sell the whole car...

I hope you also realize that that spike really isnt a huge problem, and probably makes the midrange feel alot better because its so rich through there 12-13psi will make the a/f go up, meaning more power.
 
I am not bitching about my car by any means. I just want a good reliable BC for about 10 psi with little or no spikes. Is there any decent MBC's out there?

my post was directed at KSW. 505 seems to swear by his Boost Sciences Dual Stage MBC.. and he had a GB on them for about 55. Not bad at all...
But for the most part, mbcs will spike a little.
The Halman in car is also a really nice piece, but its about 180...but allows you to adjust boost manually from the car. Very little spiking an a friends MBC.
The profec b is probably the best EBC you can get though.
 
If I want to b**** that's my fucing problem dick. And yea this mazda has gave me nothing, but problems. That's why it sucks and so does the dealer. I have no problem dumping this car and getting a 350z, yea I got it like that. I like turbo cars it's just tuning and appling more boost just drives me nut's. To be honest this car has alot of problems period. I am still going to keep the car for maybe another 2 or 3 mths and if I can't get the boost sciences controller to work then the car is gone..................
