The regular one matches what's in the tune I expect, while
the other is going to be a tuning adventure.

you can try increasing the entire MAF table by about 15-20% and put the bigger one in. Altho like someone said above, It will be a tunning ADVENTURE. Basically you are allowing more air to flow thru but the MAF will see a the same frequency(sometimes less) for any given GPS of air vs the stock MAF. So by increasing the entire MAF table by a percentage it will adjust for SOME of the changes to the MAF. It can be done, Altho it will be difficult to tune.
