has anyone used this thing... today i pump 100 octane cause i wanted too play with my sr... i was hoping to run 14psi.. so i set the gain for 28% gain to get a feel for the psi.About 12psi.. as soon as i mashed it the screen went from the usual blue... to red!!! i imediatly got off the throttle...now was that a danger warning or just tellin me im in the high boost range.and too keep going.. i really want too beat on my sr and quit babyin the slut.... mods are sr swap with walbro fuel pump,hks intake, hks bov,koyo raidiator, ichiban turbo manifold,3in elbow.hks 3inc down pipe,catco 3inc high folw cat and my beloved Circuit Sport 3inc cat back..if this matters exedy stage2..is ther anythin that might be rendering me from goin too that psi...thanks..:hsdance: :hsdance:

now was that a danger warning or just tellin me im in the high boost range.and too keep going.

You are probably about to blow the welds on the passenger floor pan... Do you really think the warning light is there to let you know that you're boost is doing awesome and to keep up the good work?

:ugh:

All joking aside, how about you try adjusting the warning to over 14psi which is what its set to by default, learn how to use the boost controller, maybe start with the manual, or maybe even type the name of the controller into google

LOL.


Definately grab the manual so you don't blow anything up. You can download it from Greddy's website.

Also, you should be adjusting your SET first and then using GAIN to smooth things out.

Are you trying to run 14psi on a stock blacktop? You're going to want larger injectors for that amount of boost.

Read the link that "statik" posted. Good info there.

Really IMHO, the Profec B spec2 isn't a very good boost controller... it's difficult to use and doesn't work at controlling boost all that well. I've been using one for about a year now... I still play with the settings trying to get it working just right; fortunately I've never overboosted yet....

I just read through that link statik posted. It lays things out in a fairly easy to understand manner. I wish I had that when I started with mine.

A lot of people are down on this controller. Granted, it is harder to get setup than others. But i've had no issues getting mine to generate consistent boost after I figured out what each of the settings does.

Once again, be careful trying to boost too much on a stock setup like yours. You'll likely blow things up because of lack of fuel.

you dont need largeer injectors for 14 psi ive been running it for months with no problems

indeed, if its a T25, 370's are fine for 14psi, as is the stock maf

It's def not as easy as a dial-a-boost, once you understand how it works and tune it properly you should have good spool with no creeping/falling off, which some boost controllers just cant do (depending on wastegate etc.)

That's true.. I have my boost relatively stable with mine, I find it still just needs little adjustments every now and then. I just don't see why GReddy couldn't have made it a little more user friendly is all....

[driftage240]

so pretty much just adjust my set then the gain to smooth shit out... thanks for all the help...even the ricey comments...:0 so safely 12psi on my setup?????

[mRclARK1]

so safely 12psi on my setup?????

12psi will be fine on a stock t25.. don't push it past 14-15psi though. A t25 isn't efficient much past that anyway, so it's not worth the risk of blowing it.

cool thanks much....
