Default Only thing is that Liam owns a ndbw.
I did not have any issues with misfires on my 2000 with the T28 kit, not even when I ran 1.6 bar of boost in 3rd and 4th gear.

Default Spike on all K03 setups?
My K03 chips never ever spike, they just hit and hold till the boost drops off in the higher rpms. I have driven in a few Xchip cars and they dont tend to spike either.

Default maybe it has to do with how the N75 is set form the facotry on certain cars
my K03 didn't spike as much and as high over requested as my GT25, but it did spike.

Default That isn't what you said here . .which is it?
"Most K03 chips have a slight boost spike when you first go wot
it will even be a little higher under a load. It will spike high then settle back down and hold till around 5K rpms where it will start to drop in boost. K03 cant hold 1.1+ bar to redline."<ul><li><a href="https://forums.audiworld.com/a4/msgs/1373911.phtml">https://forums.audiworld.com/a4/msgs/1373911.phtml</a</li></ul>

Yes it is indeed wrong. The original printed version is wrong too.
