Please help,
ive a new KK03-04 turbo, Spec-r boost valve & universal fuel pressure regulator fitted!
When my car boosts near 10psi I get thrown forward & the cars boost drops? what starts off promising ends up failing!

I have read on other forums that this could be due to ECU overboost protection that may possibly be hacked by adding a static ground to fuel pump relay

Then I discovered the Zener mod with a 4.3v or 4.7volt on the map sensor wires. However Im not convinced my A4 had a map sensor fitted?

Is a map sensor ( manifold absolute pressure ) simular/ or the same as a "Barometric pressure sensor" which I think my car may have?

Im looking for a cheap mod that can be done to fix my problem to allow me to manually set my desired boost poss 15psi on the specR valve
Thanks

 

get proper programming?

 

Your car doesnt have a map sensor. Its for either 2000+ or 2001+. You arent able to do the diode mod. Is that the stock turbo that was on the car? If its bigger your going to need a tune.

 

MAP is on 2001+

 

I have a 2000 and have a map sensor.^^^

 

are you chipped?, that would happen to me when i wasn't tuned and i would hit the psi limit for stock software. get a tune and you should be good.

 

thanks for the correction, for some reason i thought the MAP sensor started on the AWM.
