your poll is confusing. That’s why 20 people have replied to your thread but nobody has voted.
Its great you should mention this. I have seen the same thing. What that is telling you is that the car is now more efficent.
The issue comes in that your not going to see much of a power imoprovement till you get the JHM chip to go along with the zingomod.
The ECU can’t do but so much without the help of the JHM tune.
First time I drove my A4 3.0 I got it to 140+ racing a GLI on the way home from the place I purchaced it.
GLI topped out at 127 I walked away from him and my GPS said 140 and my speedomiter said 138.
That was before I replaced the CATS and exhaust and put the K&N air filter in.
My 60-120 time seems dramaticaly reduced. Since the exhaust was done.
