I have upgraded my chip in 2001 s3, now it gives around 1.5bar peak boost (it was 1.1 with the previous chip). But now I have problems with it: 1) ESP light comes on in an aggresive drive 2) Most importantly; Now there is a big turbo lag, the car does not response well to the throttle. The turbo kick comes very late when I hit the gas to the end. Need help. Are all 1.4 - 1.5 guys have that big turbo lag. I see the boost at the gauge, but it takes very long time for the turbo to kick in. It was not like that when I was doing less boost.
