07 silverado e38 injector limit/stoich trick

[camaro1]

who has done the stoich trick to get larger than 60# injectors in these ecm's, got a friends 07 6.0 max with a tvs2300, he went with 850cc injectors so we entered in the injector data and divided by .5 then doubled the stoich table and the truck runs fine when warmed up, all trims and wideband readings normal but on cold start the truck runs and idles fine but any blip of the throttle and it goes 100% lean and dies only does this for about 4-5min and till coolant gets to about 130*f

tune is 100%maf, is there something im missing for the cold start enrichment when doing the stoich trick,, i know this isnt the desired method but read about many people doing it.

I do it all the time, and it works fine. It is actually more consistent than traditional scaling too. Dial in the SD coefficients, and it'll get better. There are other possibilities, but I'd start with that.

Huh, what kind of 850's? ID 850's or something else?

Injector data is probably shoddy then.

adjusted the stoich table down .6 and re-checked the maf tuning took care of the issue
