A4 B5 1.8T question on Boost
« on: Mar 13, 18, 07:23 »
Another car question for my daily driver.
Car is a AWM 1.8T 5spd Quattro 2001 175kms

I installed a stage 1.5 ecu in the car and now have a funny issue.

Car pulls hard after 3000rpm and 1/2 throttle.  Almost feels like a old 2stroke power band.  Below this it feels average if not below avg.

DV is OEM(may be original)
N75 is OEM(may be original)
running Shell 91 fuel.
Giving a random CEL without a code(generic OBD2 reader) and will update once scanned with VAGVOM

Would either the DV going bad or the N75 going bad cause these symptoms?

Car ran ok on the stock program and now it is running 15psi boost program and does pull pretty hard in 3rd gear highway pulls testing.

any help from the Audi gods is greatly appreciated.

Did you find out what the code is?   I have the same engine/car combo.  Can do some logging with VCDS if/when you have it.    Who's tune?
