Ive heard several people say that putting a new maf sensor on the ls1 just causes problems down the road. What are these problems?

I personally was thinking of going with a bbk throttle body and a granatelli maf sensor. Is this a bad choice


FYI i currently have a FIPK intake, pacesetter LTs and a magnaflow cat back

FUN LS1

Can't say about the Granetelli, but my SLP 85mm MAF has been trouble free since I put it on a few years ago. I believe the problems arise when tuning after a head/cam swap in 'some cases'. Or if you're having trouble with a tune, you might need to swap the original back in, but I don't know why specifically. I have no second thoughts about recommending the SLP 85mm MAF sensor.

I have the granatelli 85mm and it idled a little rough when i put it in and i was running rich, but after i got it all locally tuned out its been wonderful

dont put a MAF sensor in the car that isnt stock unless you calibrate it. it works for some guys because it will lean out a rich tune. other than that its a waste of time and money. if you run it lean you can ping and cause other issues. as for the TB save your money and port your stock one

The stock MAF is good for 500 plus rwhp.

Get your stock TB ported as well, definitely worth every penny.

Not to take over your post, but if you have a bigger lid and TB and intake, why would you want to bottle-neck your intake system with a small MAF body? Im puttin in a 90/90 combo with a 90 lid right now, and ive also still hear to keep the stock MAF with that too...That makes no sense... I havent gottin a MAF yet...

go MAFless with a 90mm set up. where did you get the lid? best to my knowledge, noone made a 90mm lid...in that case though you are correct it will be the bottle neck

thanks

not to sound like to much of a noob dumba$$ but how does one go about porting a throttle body? who does it? how much?

you can buy one for about 100-150 or if you are handy enough with a dremil and have about 2 hours to kill you can do a really nice job. i did mine that way and hand smoothed it. took a long time but it was well worth it. there is a lip in there BEFORE the tb blade that you can flatten out, if oyu look in there you will see what i am talking about
