When you hit 5,000 rpm's or so, do you hear a faint beep? If so, thats your boost cut kickin' in. Mine does the same.
I was wondering if that was boost cut.I didnt think it was cause my waste gate line tore a few weeks ago and it was more violent when it boost cut..But in hindsite maby it was detonating as well.When you hit 5,000 rpm's or so, do you hear a faint beep?

I checked them and can not find any..I'll proablly just pressure test them and see what happens.But you guys are proablly right about the boost cut.you are not going to get full boost in first and second. your engine makes more boost when under load in a higher gear. you are probully hiting boost cut. check all of your plumbing for cracks or tears.
on stock ecu i hit boost cut in second to fifth at around ten psi, it sounds like boost cut but then again, keep your mind open.It creeps up to 10ish..Thats why I didnt think it was boost cut..But my gauge might be off.
I'm running a mbc.And no on the check engine lights.on stock ecu i hit boost cut in second to fifth at around ten psi, it sounds like boost cut but then again, keep your mind open.
oh yeah are you running a mbc or stock boost siliniod?
have you tryed to pull codes/is the check engine light on?
It doesn't really matter what your PSI is, if the VAF door is open all the way, you will experience fuel cut (not boost). It could be at 9psi, or could be 16psi, it all depends on when that VAF door touches the sensor.
Not sure on these. I wouldn't hack the VAF, this is just personal preferenceHas anyone opened the vaf up?..On the Ford 2.3T's theres a spring you can tightin up that makes the door harder to open.
There is one available, it's megasquirtI have access to a wideband so I might try this and see what the a/f's are...Does the chip that gets rid of boost cut add fuel as well? If not then I cant see what the problem would be.A freeware tuning system would be great for this car.
The software might be free..But the hardware not so much...There is one available, it's megasquirt
