Default KL racing chip experiences?

A while back I picked up some kl racing chips for my 940. ECU and ezk chip, both with stickers labelling them for 465cc injectors and a 3" amm. Currently running chips in my wagon with the prescribed injectors and maf and I've had nothing but issues. With a 3" amm (both a genuine 012 unit and a 016 mounted in a 3" pipe) the afr reads almost 20 at idle. With the stock maf idle is 11-12, 14 at cruise and 10-11 at wot. Sluggish overall, lugs hard at idle. Has anyone else used their chips? I'd love to pin this down to user error at some stage before I take things back to closer to stock or find new chips.

Correct impedance injectors. Correct fuel pressure.

Make sure you are using the correct EZK and fuel ECU for the chips. How is the fuel pressure and have you recently changed the filter? Did you double check and make sure there are no missed pins when you installed the chips?

I have a set of these (no shame). As far as I can tell the MAF lookup tables are untouched, so would actually make sense it runs best with the 016.

edit: They're also sized for more like a 370cc injector, for whatever reason.

The label on the chips matches my ECU, ezk label calls for a 207/219 ezk but I've added a daughterboard to my 148, I believe that should be compatible. Just pulled the chips to check and my pins are good.

Huh, that's interesting. I've realized that while the chips call for 465cc injectors and mine technically are, that's at 3.8bar, not the stock 3bar. My next troubleshooting step was going to be grabbing that 3.8bar regulator, but maybe I ought to source some 370cc injectors instead. Thanks!

Those chips, as many others are what I would call "bogus chips".
Nothing that affects fuelling is changed, only rpm limit and boostcut are altered.
Overpriced 5 dollar tuning....
