If your MAF sensor under-reads because of (some) induction kits, that would explain the lower than expected injector size in the ECU compared with the real size.

Well, I have the Buschur air filter (no hardpipe). I suppose there are minor changes to the maf reading. My scaling right now for the inectors are 886.

Doesn't sound bad, JDM and US vary as well, but with a cone filter I'm commonly setting it a good 10% below the real injector size without adjusting the MAF scalings.

Yep. I used my scaling and latency on 3 cars so far with cone filters with good success. RedLanEvo, sorry my values didn't work for you.
