Whos running boosted on a recalibrated stock pcm? Hows it working? what is your set up? If you run twins do you have to run in speed density?

You don't have to run sd until the maf maxes out, but it works better if you do.

and when will the maf start to max out? how does the pcm read two mafs on a twin set up? or dont you need to mafs? thanks

Y2Khawk is the only one with two MAFs. he only did it because he was maxing a single one out.
if your below the 62lbs/min you can get away with one, though iif you want two good luck on making it yourself, luckly HP tuners will be offering a SD set up soon.

So on a twin set up do you just run one maf on the intake side of one of the turbos? or do you use one and blow through it? thanks for the help

you would want to run 1 on each turbo, or one as a blowthrough.

most people would never put the time into having 1 drawthrough on a twin setup.

I have discussed running 1 maf on 1 turbo of a single with some scaling for a ford setup, never tried it, but it could work.

OK so can I just tune the pcm for speed density and eliminate the maf ? What should i do. It looks like i will have my combo ready to go long before i can afford the stand alone. so i was hoping to run the stock pcm and keep the boost low. What route should i take
