i just installed the boost machine.
but the boost goes back and forth from 8PSI to 15PSI. hm.. i want this to be set at 15PSI for 180hp audi tt.
i don't know why it swings back and forth. anybody know what i should do??? it works great when i reduce the boost, but once it hits over the stock boost level which is 10PSI, then it goes back and forth. hm. is there anything that controls the boost except the N75??? please help me

Are you chipped or anything? Or are you just trying to boost 15psi on a stock car?

If you are stock the ECU will restrict the boost from getting too high, r u chipped?

jewooni

no mine is stock.
i read the article saying that it works better with the stock setup.
does it have to be chipped to run this boost machine??
oh no.. please help

jewooni

yes my car is stock, and i just want constant 14-15PSI on my car.
i don't want to any further.
that is my goal.
please help.
thanks

conservative boost map. The BM will tend to keep the boost up bringing the boost over the allowed threshold causing the ECU to bring the boost down. So set the Regulator lower and it will probably work. Do u have a Boost Gauge & Vag-Com?

yes, i do have a boost gauge.
but i don't have VAG-COM
what does VAG-COM do??
seems like everyone has one.

U probably have a DTC (Diagnostic Trouble Code) in your ECU, you will need a VAG-COM to clear the code.
This maybe the reason why you are not getting the boost needed.
