i need some stumbling help

so with specs in sig, i cant get it to run right, it stumbles alot and what not, also got a maf high code, i raised all the maf values by about 10 points total that helped alot but i get the code.. is this because maybe the maf value is higher then the maximum air flow vs rpm? i dataloged a whole session if someone could give me a hint what to look for specifically? thanks in advance!

-also are blms's a direct reading from o2 sensor?

With a 10+:1 motor things are just that much more critical to get right. If you're talking about stumbling with throttle application, then look at the AE vs MAF, and AE vs TPS. 'N you shouldn't need much timing, ie alot of the MAF .bins run alot more timing then what you'd need.

Yes.

Raising the MAF values in the MAF tables makes things richer. If you find yourself making whole sale changes you might dither with the Injector Constant.

u think the stumble is a lean condition? i cant find any tables to do with ae (accleration enrichment) except for ae factor vs change in lv8.

edit: now i see some accel enrich vs etc... but nothing for what you say ae vs maf? and no ae vs tps? where am i missing this?
