It was what I thought it was. The PFC was set on sequential. I put it back on non-sequential and bingo, I starting making over .4 bars of boost. The problem is, Im playing with this garbage home depot boost controller and the only way I can make over .4 is when the boost creeps. I have a ported wastegate so this doesnt make a whole lot of sense to me. I've gotten it to creep all the way to .66 (as read by the commander) and it seemed to stop dead solid right there. It jumps to .4 real quick, then does its creep bullshit to .66. I’m still playing with the boost controller to try and get it to creep to .8, but why is it creeping? When it used to make 10psi it'd just shoot right to .8.

 

well... when it was making 10psi perfectly... what did you change/ add before it started making only .4bars?

 

You know, I'd be giving alot more info than I am right now but, RX7Wishing's avatar is REALLY messing up my concentration(just messing with you man ). But anyway, on the PFC for non-sequential mode, I'm not sure if it has a wastegate cycle percentage adjustment just like it has on sequential, then just raise the percentage until you reach boost. Since you have a MBC, it doesnt control wastegate actuator controls, but the PFC can. So try to raise the wastegate cycle percentage on the PFC if you can and see what happens. I'm having a boost issue too, though I'm seq. and am having a 10-5-5 issue.

What is that under the commander? I dont have a manual. Is it the boost settings where it has the 4 different values for primary and secondary? Which of those 4 do I change?

 

There are four settings on the PFC. There are 2 settings, one has boost pri. - .80 and sec. 70. The wastegate cycle settings are 54/64. The second setting is .90 and .80 and the wastegate cycle is 64/70. Raising the wastegate cycle percentage will get you to boost more as the wastegate opens less. BE CAREFUL not to raise the boost too high. And make you you can afford anything you can break . Good luck with your boost problem.

i was getting boost problems in my car because i hookes the waist gate up after the throttle body instead of before it (because of my garbage *** turbo). also it was hooked up on the top of the waist gate instead of the side

 

Can you rephrase what you just in more detail, and then elaborate please?

Jeremy

 

first of all, its wastegate hahaha

secondly, how big did you port that wastegate? are you sure you did it correctly? do you have pics of how big you made it?
