Ok, i thought originally i was getting a fuel cut. but now when i get inconsistent boost. sometimes all the way to 12.5, next only to 10, but it aslo jerks sometimes like an weird fuel cut. So obviously the acclerations it erratic as well. i know the long list of places to look, but was hoping someone could give a better place to start. https://www.nopistons.com/forums/pub...R#>/unsure.png

does it always switch over to the second turbo?



mike

yes i think so. i was thinking 3 things, leak somewhere, turbos going, bad ECU

well if it always switches the seond turbo, and has inconsistent boost, it cant be a leak, or the turbos. it could be a bad wastegate solenoid



mike

why can't it be a leak?

because if it was a leak you would not get a consistant changeover to the second turbo. Something would be fucked up before then.

OK, drove it again, now is seems like i only get the first turbo in 1st and 2nd, but when in 3rd looks like i got both. Very weird.

The secondary comes on at 4500 rpm. Is it coming on line?

yes very quick blip at 4500, when it is running right it seems to go 12 - 10 -11, but it does not do that consistently. seems to be more problems when it is cold. perhaps a gasket?



thanks FD3boost, know you been through it all.

ok i don't know if it fixed itself. but most of my powerband is beyond 5000 i get a strong surge at 5000 is that normal?
