i have a 104 lide, 102 fast intake and 102 trottle body, the stock maf won't hurt my hp until i max it out???, tell you why i have the stock maf now before you ask. i have been trying to get ride of some bucking with the 100 mm maf i had and i could not. my e-mail tuner told me to try my stock maf to see, and almost no bucking to speak of. just that my but-dyno tells me i have lost a bit.

stock MAF definitely sounds like the restriction in your intake track, but I don't know the rest of your setup. I havent seen much of a before/after comparison from swapping MAF's only. I would say if you already have the bigger maf, and the rest of the setup is big like the 102 stuff you posted, then I would focus on working out the bucking.

that is why i want to kno the max that the stock can take, not saying that it is a restriction but i do want to find out, have been trying to tune the large maf with 2 tuners, it was the ideal of the 3rd to try a diferent maf to see if the bucking would go, this is all by e-mail tuning

check one of my logs and at 6170rpm i was at 96kpa, check before i started the car and was 101kpa. at one point on a acceleration log it was at 101 then started to drop down to 96 as rpm went up.

You should be seeing 100+ for most of the run with your intake setup. I know you said you had bucking with the 100MM MAF, but is it okay under WOT? I'd be curious if you swapped that on and made another pull, if you'd suddenly see it stay at 100+. Of course this assumes the tune is acceptable for the new MAF at WOT.
Edit...I should clarify. Are you just a bolt-on car or do you have heads/cam too?

Ah, I use EFI Live. Otherwise, I would have looked at your logs. You just need to try and gauge from the logs if it appears like a significant restriction. I would think you're probably okay, but it sounded like with the stock MAF you were at 96kPa and then it went down, whereas the 100mm stayed around 98-99.
