thats true. but i only use bsfc charts for acceleration purposes. i have been downshifting 2-3 gears to pass but recently stopped doing that. i can pass really well in top gear noe no problem with car churning about 3000rpm at near wot. my car is maf equipped and not map. although sg2 still reports map!? i also have programmed for maf in g/s. can that be helpful?
