I tried staying with the stock boost system way to long -- go to ebc if you want reliable control.

well it connects to the stock ecu harness and takes control over the oem (or pfc) boost control, no external boost control solenoid.

but you got a good point about the feedback operation to maintain boost instead of the duty cycle like the pfc does... i might put it back and try how it does.

Lots of good comments in this thread. Very few know how to tune the transition using datalogit (I'm not expert but have played with it a lot) and you can do amazing things with that tuning. Comment to Stix -- with the BNR's I found the primary is soo strong i actually moved the transition up rather than down so that I have full/quick primary response longer and it doesn't bring on secondary until you really need it. BNR primary has no problem going 15+ up to a good 4-5k. Sorry, hard to explain some of this clearly. . .

mine transition seems to have moved up by itself when mine were installed, i think he said it was to lessen the lag

So how does one tune the transition??

After mine was tuned it had 14.5-13.7-14.5 with just a flick on the boost gauge...Buuut then the engine blew :wallbash: :wallbash:
