That's fine. You'll need a 2 bar MAP if you're running about 16-32 PSI of boost. If you run less than 16, then 1 bar is fine, and about 30-46 PSI you'll need 3 bar.
But that doesn't change the fact that you should have the MAF as well, and the cold start/idle tables should be pretty much the same as stock. Cold idle isn't making any boost, so it doesn't matter how many bar your MAP can handle.

My ecotec's wiring came straight out of a 2004 cavalier .Except for adding HP tuners , it is all stock .No MAF , just a MAP .It is definitely considered a drawback having to tune with MAP , MAF is considered better .

So can I have BOTH a map and MAF sensor?

I would think a stand alone setup like you have would have provisions for both . You have to dig in to the specs from the manufacturer to find out .

You SHOULD have both already, yes.
Everything I see on Alpha Fab's site indicates their setups use both. And the stock LE5 used both, as far as I can tell from my quick searching on the net.

It's right there in the list on the page you linked to. Either you have a MAF and don't realize it, or your installer left it out and that's causing problems. It sounds like you need to talk to your installer and maybe Alpha Fab to get the issue resolved.

So i talked to Alpha fab, when i bought the kit, the tune and design was based only off a 2 bar map. So my kit did come with everything it needed. There new version of the same kit comes with both the map and maf. So thats what happened there.
I talked to my mechanic, i asked him if we added a maf if that would make the engine run better. He says he would have to re-tune everything but it wouldnt make it run better, the engine is running perfectly except for the cold start which he's fixing this weekend. Once he throws his o2 wideband kit into the car he will have that fixed, he says if i want i can add a MAF later and re-tune the car but i would get the same results as what im getting now for performance and gauge numbers. So we will see what happens after this weekend.
